Abstract: An antenna (200) for use with portable communication devices (300) includes a transmission line having a length substantially smaller than the quarter wavelength at an operating frequency. The transmission line includes a signal conductor (206) and a ground plane (204). A physical connection (210) made between the signal conductor (206) and the ground plane (204) provides for the transmission line to function as a quarter wavelength antenna without needing additional matching circuits.

Abstract: A receiver (200, 400) implements improved channel estimation. The receiver (200, 400) demodulates a transmitted signal, and makes an initial channel estimate (115). The receiver (200, 400) then makes a hard decision (301) as to whether the channel estimate was correct and groups samples representing the decision. A vector sum of the group of samples is computed (302), and each sample is compared to the vector sum (303). The sample having the largest projection on the vector sum is retained (304), and the other samples are considered noise, and are thus discarded (305). After obtaining a predetermined number of retained samples (306), the retained samples are used to generate a new channel estimate (226). Since the noisy estimates are discarded, the new channel estimate (226) contains fewer errors than the initial channel estimate (115). The new channel estimate (226) is used to generate decoded data (250).

Abstract translation: 接收机（200,400）实现改进的信道估计。 接收机（200,400）对发送的信号进行解调，并进行初始信道估计（115）。 然后，接收机（200,400）作出关于信道估计是否正确以及表示该决定的组样本的硬判决（301）。 计算样本组的矢量和（302），并将每个样本与矢量和（303）进行比较。 保留矢量和上具有最大投影的样本（304），其他样本被认为是噪声，因此被丢弃（305）。 在获得预定数量的保留样本（306）之后，使用保留的样本来产生新的信道估计（226）。 由于噪声估计被丢弃，所以新信道估计（226）包含的误差小于初始信道估计（115）。 新信道估计（226）用于生成解码数据（250）。

Abstract: A computational array (120) includes at least one computing element (130) that calculates multiple terms in a polynomial. The computing element (130) obtains an input value of each variable in each of the multiple terms and a subscript uniquely identifying the variable. The computing element (130) reads a term identifier and an exponent corresponding to the variable at a memory location based on the subscript. The computing element (130) multiplies the input value by a selected weight value and multiplies the input value by itself a number of times based on the exponent and stores the result at a memory location corresponding to the term identifier. The computing element (130) calculates multiple terms by distinguishing each of the terms with the term identifier.

Abstract: A demodulator (18) which receives digital representations of a received signal converts those signals into analog signals (53) in a pair of multiplying analog-to-digital converters (MDACs) (21, 22). The analog signals are then combined in combiner (26) by subtracting the first analog signal from the second analog signal (54). The summed signal is normalized (55) in quantizer (27). The output from the quantizer (27) is accumulated (56) in an n-bit accumulator (28) as regulated by a clock input (Fclock). The output of the accumulator (28) is used as a programming input (57) to the MDACs (21, 22).

Abstract: A system (10) and method for simultaneously enabling a voice and a data session has a voice data modem VDM (200), coupleable to a data port (255), a voice jack (240), and a telco jack (280). The data port (255) is connected to data terminal equipment, DTE (100), the voice jack (240) is connected to a telephone, and the telco jack (280) is connected to a telephone network (120).
