Abstract: The disclosure relates to a collaborative demand-based dual-mode Wi-Fi network control framework that may optimize wireless power and performance on wireless devices that may support multiple Wi-Fi networking technologies. In particular, a high performance Wi-Fi link may be reserved to services or applications that have substantial quality of service (QoS) requirements and conventional Wi-Fi links may be utilized to transfer data for services or applications that have typical performance requirements. For example, bandwidth requirements associated with forward traffic may be measured according to sizes and latency requirements associated with the forward traffic and the appropriate Wi-Fi networking mode may be controlled according to the forward traffic bandwidth requirements in combination with the average bandwidth and average retransmission rate associated with the conventional Wi-Fi links, among other factors. Furthermore, when no forward traffic needs to be transmitted, all Wi-Fi subsystems may enter a low power state.

Abstract: A power amplifier develops a modulated high power signal by summing the outputs of multiple voltage controlled oscillators. A phase control circuit synchronizes the phase relationship of multiple voltage controlled oscillators. The voltage control oscillators provide amplitude modulation of an output signal of the voltage controlled oscillator by adjusting transconductance of amplification devices of the voltage controlled oscillator. Another embodiment of the power amplifier provides buffer circuits at the outputs of the voltage controlled oscillators. The gain or delay of the buffer circuits is varied to provide amplitude modulation of the power amplifier.

Abstract: Soft symbol decoder algorithms for multiple input, multiple output (MIMO) receivers reduce the search complexity by searching over fewer than all possible combinations of transmitted symbols to compute log metrics for each transmitted bit from each transmit antenna. In one algorithm, a sub-optimal set of transmitted symbols is computed and the transmitted symbols are restricted to neighboring constellation points of the sub-optimal set. In another algorithm, all constellation points are searched for every antenna except one. In yet another algorithm, constellation points are searched excluding more than one antenna. The non-searched antenna(s) can be handled by either a bit stuffing or a soft slicing technique.

Abstract: Demodulator architectures for processing a received signal in a wireless communications system. The demodulator includes a number of correlators coupled to a combiner. Each correlator typically receives and despreads input samples (which are generated from the received signal) with a respective despreading sequence to provide despread samples. Each correlator then decovers the despread samples to provide decovered “half-symbols” and further demodulates the decovered half-symbols with pilot estimates to generate correlated symbols. The decovering is performed with a Walsh symbol having a length (T) that is half the length (2T) of a Walsh symbol used to cover the data symbols in the transmitted signal. The combiner selectively combines correlated symbols from the assigned correlators to provide demodulated symbols. One or more correlators can be assigned to process one or more instances of each transmitted signal. The pilot estimates used within each assigned correlator to demodulate the decovered half-symbols are generated based on the signal instance being processed by that correlator.
