Abstract: A system and method for noise suppression in a speech processing system (108) is presented. A gain estimator (220) determines the gain, and thus the level of noise suppression, for each frame of the input signal. If no speech is present in the frame, then the gain is set at a predetermined minimum. If speech is present in the frame, then gain adjuster (224) determines a gain factor for each channel of a predefined set of frequency channels. For each channel, the gain factor is a function of the SNR of speech in the channel. The channel SNRs are generated by an SNR estimator (210b) based on channel energy estimates provided by an energy estimator (206b) and channel noise energy estimates provided by a noise energy estimator (214b). The noise energy estimator (214b) updates its estimates during frames in which no speech is present, as determined by a speech detector (208).

Abstract translation: 提出了一种用于语音处理系统（108）中的噪声抑制的系统和方法。 增益估计器（220）确定输入信号的每个帧的增益，并因此确定噪声抑制的电平。 如果帧中没有语音，则将增益设置为预定的最小值。 如果帧中存在语音，则增益调整器（224）确定预定频率信道组的每个信道的增益因子。 对于每个通道，增益因子是通道中语音的SNR的函数。 信道SNR由SNR估计器（210b）基于由能量估计器（206b）提供的信道能量估计和由噪声能量估计器（214b）提供的信道噪声能量估计来生成。 如由语音检测器（208）确定的，噪声能量估计器（214b）在其中不存在语音的帧期间更新其估计。

Abstract: An apparatus for providing authentication of a mobile station in a wireless communication system. The present invention takes the number dialed by the mobile station user and computes the 24 bit number (AUTH_DATA) for authentication in accordance with a hashing function that has the following characteristics. The hashing function takes as its input at least the entire dialed digit string contained in the request for service and the number of digits. In a preferred embodiment, the ordering of the digits affects the results, as well as, the values of the digits. The preferred embodiment of the hashing function also accepts some or all of the mobile station identifier data. The function provides as output a number of suitable size for input to a second calculation of an authentication signature, such as the 24 bits required for AUTH_DATA. The output number is created in such a way that there is a minimum likelihood that other sets of dialed digits may create the same result.

Abstract: A subchannel within a CDMA signal is provided together with a system for receiving and decoding this subchannel. A message is transmitted over the subchannel by applying a sequence of phase rotations to the user data. A single subchannel message can be transmitted during each 1.25 ms segment of user data, resulting in transmission rates of up to 800 messages per second over the subchannel. Each message corresponds to a fixed sequence of phases, called a phase codeword, used to rotate the user data each time that message is sent. When only two phase codewords are used, the effective data rate for the subchannel is 800 bits per second, but higher data rates may be achieved by increasing the number of codewords used by the subchannel. The subchannel may be decoded by correlating the user data with each of the possible phase codewords.

Abstract translation: 与用于接收和解码该子信道的系统一起提供CDMA信号内的子信道。 通过将一系列相位旋转应用于用户数据，在子信道上传送消息。 在每个1.25毫秒的用户数据段内可以发送单个子信道消息，从而在子信道上每秒传输高达800个消息。 每个消息对应于固定的阶段序列，称为相位码字，用于在每次发送该消息时旋转用户数据。 当仅使用两个相位码字时，子信道的有效数据速率为每秒800比特，但是可以通过增加子信道使用的码字的数量来实现更高的数据速率。 可以通过将用户数据与每个可能的相位码字相关联来对子信道进行解码。

Abstract: A novel and improved method and apparatus for providing an interface to a digital wireless telephone system compatible with standard analog wire line telephones (10), analog wire line fax machines (12), and computer modems (13) is described. At the start of a telephone call, a data pump (52) interprets the digits dialed, and if a first set of digits are received, a control system (56) configures the data pump for processing analog fax data.

Abstract: The present invention is a novel and improved method and apparatus for decoding a frame of digital data which contains redundant information provided to validate the decoding operation. In the present invention, a frame of data contains information bits and cyclic redundancy check (CRC) bits. The received frame is decoded and a check is conducted by CRC check (84) to determine whether the CRC bits correspond correctly for the decoded information bits. If the decoded frame passes the CRC test process, the decoded frame is provided to the user. However, if the decoded frame does not pass the CRC test, then at least one additional decoding process is performed on the received frame. In the first exemplary embodiment of the present invention, if the CRC test is failed, a noise vector of a predetermined set of noise vectors generated by noise generator (80) is summed with the received frame and the resultant frame is decoded for a second time. In the second exemplary embodiment of the present invention, when the CRC test fails, a set of the received symbols are replaced with symbol erasure indications by erasure generator (162).

Abstract: A system (2) uses conventional text messaging capabilities of cellular telephone systems to embed one or more call-back telephone numbers. A start delimiter (204) is used to separate a text data portion corresponding to the call-back telephone number (208) from the text message (214). A termination delimiter (210) may be used to indicate the end of the text data portion corresponding to the call-back telephone number (208). Multiple text data portions, corresponding to multiple call-back telephone numbers, may be inserted using multiple start delimiters and termination delimiters. A text parser in the cellular telephone searches the text message for the start delimiter and extracts the text data portion corresponding to the call-back telephone number. The cellular telephone user selects a desired call-back telephone number, which may be placed in a dialing queue for simplified communications between the cellular telephone and a destination corresponding to the selected call-back telephone number.

Abstract: The cellular telephone (10) includes an equalization filter (54) for adjusting the frequency response pattern of an audio signal provided to the speaker (24). The equalization filter (54) operates in response to user control to allow the user to adjust the frequency response pattern as desired. In one specific embodiment, the cellular telephone (10) includes an equalization filter table (56) for storing sets of audio frequency filter parameters, and the user merely selects one of the sets of filter parameters by pressing a corresponding button on a front control panel (11) of the cellular telephone (10). In other embodiments, the cellular telephone (10) includes an equalizer scroll bar allowing a large number of sets of filter parameters to be accessed. The equalization filter (54) and the filter table (56) may form part of a digital signal processing unit (42) also including vocoder encoders (50) and decoders (52). By providing an equalization filter (54), a cellular telephone (10) user may adjust the frequency response pattern of received signals to compensate, for example, for local noise or for hearing abnormalities to thereby allow the user to hear the other party to a telephone call more clearly. Even in the absence of any significant noise and even for a user having normal hearing, the user may still gain at least a perceived listening improvement.
