    Abstract: An ambient country identifier (ACI) signal can be used to automatically provide location awareness for a WLAN device. If an ACI signal is detected, then the WLAN device can configure itself to comply with channel and power settings for the country having the detected ACI signal. After detection of the ACI signal, the WLAN device can be "locked" to the country having that ACI signal, thereby ensuring legal operation of the WLAN device even after subsequent restarts. If an ACI signal is not detected, then the WLAN device can be configured in a default mode, e.g. an "open mode" in which end users can configure the WLAN device by entering a country of operation or a "common mode" in which the channel and transmit power settings meet global spectrum usage requirements.

    Abstract translation: 环境国家标识符（ACI）信号可用于自动提供WLAN设备的位置感知。 如果检测到ACI信号，则WLAN设备可以配置为符合具有检测到的ACI信号的国家的信道和功率设置。 在检测到ACI信号后，WLAN设备可以“锁定”到具有该ACI信号的国家，从而确保WLAN设备的合法运行，即使在后续重新启动之后。 如果未检测到ACI信号，则可以将WLAN设备配置为默认模式，例如， 最终用户可以通过输入操作国家或通道和发射功率设置满足全局频谱使用要求的“共模”来配置WLAN设备的“开放模式”。

    Abstract: A frequency synthesizer and a method for frequency synthesis are disclosed. The frequency synthesizer comprises a voltage controlled oscillator for generating an output signal having a synthesized frequency, and a prescaler connected to the VCO for receiving the output signal and providing a feedback signal. The prescaler programmatically selects between an integer divider value and a fractional divider value to divide the synthesized frequency of the output signal.

    Abstract: A radio-frequency (RF) integrated circuit is described. In one embodiment, the IC comprises multiple metal layers forming multiple transistors on a non-epitaxial substrate. The transistors are step and mirror symmetric. Also, the RF signal lines are on a top metal layer above all other metal layers and the power and ground planes are on a bottom metal layer below all other metal layers. The top and bottom metal layers are separated by a shield that extends beyond the RF signal lines by a distance that is at least the same distance that the shield is away from the RF lines. Low frequency signals are on signal lines below the top metal layer.

    Abstract: C:\4RPonbDLCC\DER\3708293_1.DOC-2216/2I I A method for operating a communicating station in order to transmit information through a communication medium using a set of channels, wherein the channels have 5 respective carrier frequencies, the method comprising: determining a list of one or more of the carrier frequencies over which transmissions are to be attenuated; encoding information bits according to an error correction code in order to obtain coded bits, wherein the coded bits represent the received information bits with redundancy; 10 interleaving the coded bits to obtain interleaved bits; mapping blocks of the interleaved bits to corresponding sets of complex numbers, wherein each set of complex numbers includes one complex number for each of the carrier frequencies; modifying each set of complex numbers by attenuating one or more of the complex 15 numbers in the set that correspond to the one or more carrier frequencies on the list, wherein said attenuating includes scaling the one or more complex numbers so that their amplitudes are less than a predetermined amplitude level; computing an inverse Fourier transform of each modified set of complex numbers to obtain a sequence of time-domain samples; and 20 transmitting a time-domain signal over the communication medium based on the sequence of time-domain samples.

    Abstract: An interleaving/de-interleaving scheme for providing redundancy with both time and frequency diversity to data in OFDM symbols in a data transmission system. On the transmit side, encoded data to be modulated onto carriers in OFDM symbols is interleaved by storing the encoded data in an interleaver memory and reading multiple copies of the encoded data from the interleaver memory so that the encoded data copies are spread in time on non-consecutive symbols and in frequency on non-adjacent carriers. On the receive side, the multiple copies of the OFDM data are received, and phase noise computations are used to combine the multiple copies (in either metric or phase angle form) into one. From the combined copies a single metric value to be used in decoding the OFDM data is produced.
