    Abstract: A novel and useful radio frequency (RF) front end module (FEM) circuit that provides high linearity and power efficiency and meets the requirements of modern wireless communication standards such as 802.11 WLAN, 3G and 4G cellular standards, Bluetooth, ZigBee, etc. The configuration of the FEM circuit permits the use of common, relatively low cost semiconductor fabrication techniques such as standard CMOS processes. The FEM circuit includes a power amplifier made up of one or more sub-amplifiers having high and low power circuits and whose outputs are combined to yield the total desired power gain. An integrated multi-tap transformer having primary and secondary windings arranged in a novel configuration provide efficient power combining and transfer to the antenna of the power generated by the individual sub-amplifiers.

    Abstract: The invention provides a multi-band antenna structure for use in a wireless communication system. The antenna structure includes integrated inductive elements and capacitive elements that function as a tuned circuit to allow the antenna structure to operate in multiple frequency ranges. In particular, the capacitive elements electromagnetically couple to the inductive elements. The capacitive elements provide the inductive elements with parallel capacitance at a given set of frequencies, thereby providing the antenna structure with frequency selectivity. At a particular frequency range, the inductive elements act as short circuits, thereby lengthening the radiating elements, which radiate energy at the particular frequency. At another frequency range, the inductive components act as open circuits, virtually shortening the radiating elements in order to radiate the higher frequencies. In this manner, the multi-band antenna structure operates within multiple frequency ranges.

    Abstract: In general, this disclosure is directed to techniques for remotely controlling a transmitter-side rate adaptation algorithm. According to one aspect, a method includes detecting, with a receiver device, that a packet received from a transmitter is corrupted. The method further includes sending, with the receiver device, a positive acknowledgement for the packet to the transmitter in response to at least detecting that the packet is corrupted. According to another aspect, a method includes determining, with a receiver device, a targeted outcome for a rate adaptation algorithm performed by a transmitter. The method further includes using, with the receiver device, positive acknowledgements to remotely control the rate adaptation algorithm performed by the transmitter based on at least the targeted outcome.

    Abstract: The invention provides a receiver for use in a wireless communication system that substantially reduces mismatch between an in-phase (I) component and a quadrature (Q) component of a received signal. The receiver achieves this by sharing or "ping-ponging" an analog-to-digital converter (ADC) between the I and Q components. By sharing a single pipelined ADC between the I and Q components, both the I and Q components are processed by the same circuitry inside the pipelined ADC thereby eliminating many dominant sources of I-Q mismatch. The pipelined ADC operates at approximately twice the speed as other circuit components. Consequently, I-Q mismatch, which negatively affects performance, may be substantially reduced. At the same time, system complexity, cost, and power dissipation are reduced by eliminating an additional ADC typically used to process the I and Q components in parallel signal paths.

    Abstract translation: 本发明提供了一种在无线通信系统中使用的接收机，其基本上减少了接收信号的同相（I）分量和正交（Q）分量之间的失配。 接收器通过在I和Q组件之间共享或“乒乓”模数转换器（ADC）实现这一点。 通过在I和Q组件之间共享单个流水线ADC，I和Q分量由流水线ADC内的相同电路处理，从而消除了许多主要的I-Q失配源。 流水线ADC的工作速度大约是其他电路组件的两倍。 因此，可以显着地减少对性能的负面影响的I-Q不匹配。 同时，通过消除通常用于处理并行信号路径中的I和Q组件的额外ADC，可以降低系统复杂性，成本和功耗。

    Abstract: A speech compression/decompression system and method which do not require special hardware are described. The compression unit represents an input audio signal (19) as a collection of parameters, wherein the parameters are a remnant excitation pulse sequence (27), a set of spectral coefficients (A) and a set of pitch parameters (B & C). The decompression unit utilizes the pitch parameters and remnant excitation pulse sequence to produce a reconstructed excitation signal. The decompression unit also utilizes the spectral coefficients to filter the reconstructed excitation signal into a speech waveform. The compression unit includes a short-term predictor (22), a two-step long-term predictor (24) and a multipulse analyzer (26).
