Abstract: Wireless devices may contain multiple radio transceivers, each conforming to different communication protocols. A first transceiver conforming to a first communication protocol in a first wireless device may be able to receive, detect, and/or decode messages transmitted by a second transceiver in a second wireless device conforming to a second communication protocol. The first transceiver may communicate received, detected, and/or decoded information to a different transceiver in the same first wireless device, thus enabling the collocated transceivers to work in concert efficiently. A wideband transceiver using a set of multiple sub-channels in parallel may receive, detect, and/or decode messages transmitted by a narrowband transceiver using a set of multiple channels serially, thereby reducing scan time and power consumption.

Abstract: A single receive chain of a MIMO receiver is activated during a low power listen mode. Upon detecting a legacy short training field (L-STF) in a received packet, the single receive chain performs a first frequency estimation, and activates one or more additional receive chains of the MIMO receiver. The MIMO receiver uses maximal ratio combining (MRC) to receive the signal using the first receive chain and the one or more additional activated receive chains, wherein the MRC is based, at least in part, on the first frequency estimation. The MIMO receiver may determine whether the received packet is a high throughput/very high throughput (HT/VHT) packet, and if not, deactivate the one or more additional receive chains. In one alternative, the additional receive chains are not activated until determining that a HT/VHT packet has been received.

Abstract translation: MIMO接收机的单个接收链在低功率监听模式下被激活。 在接收到的分组中检测到遗留短训练场（L-STF）时，单个接收链执行第一频率估计，并激活MIMO接收机的一个或多个附加接收链。 MIMO接收机使用最大比率组合（MRC）来使用第一接收链和一个或多个附加的激活的接收链接收信号，其中MRC至少部分地基于第一频率估计。 MIMO接收机可以确定所接收的分组是高吞吐量/非常高吞吐量（HT / VHT）分组，如果不是，则去激活一个或多个附加的接收链。 在一个替代方案中，在确定已经接收到HT / VHT分组之前，不激活额外的接收链。

Abstract: An apparatus is disclosed comprising collocated primary receiver (PR) and a time synchronized receiver (TSR), with a Low Noise Amplifier (LNA) configured by a LNA gain control signal to create a shared amplified signal sent to the PR and the TSR for them to concurrently receive packets. The TSR is configured to generate a timed signal strength prediction signal based on the shared amplified signal and the LNA gain control signal. The primary receiver is configured to generate the LNA gain control signal based, at least in part, on the timed signal strength prediction signal. The PR may include a spread spectrum receiver, and the TSR may include a frequency hopping receiver.

Abstract: Techniques are disclosed relating to oscillator settling time allowance. In one embodiment, an apparatus may include an oscillator and oscillation detection and control circuitry. The oscillation detection and control circuitry may be configured to awaken an oscillator at a predetermined time and detect an edge transition of oscillations. The oscillation detection and control circuitry may further be configured to measure the time from the power-on indication to edge transition detection. In one embodiment, the oscillation detection and control circuitry may be configured to store the measured time and use the measured time instead of the predetermined time for subsequent oscillator awakenings. In some embodiments, the apparatus may further include circuitry configured to compensate for an expected oscillator settling behavior.

Abstract: Transient distortion is compensated for by multiplying an exponentially-decaying phase shift onto the distorted waveform. The exponentially decaying phase shift waveform is patterned after the transient which typically takes the form of an exponential and occurs upon introduction of power to a circuit or circuit component. A digital circuit produces an appropriate exponentially decaying waveform which is used as the input for a look up table whose output is a complex sinusoidal waveform capable of compensating for the distortion. The complex sinusoid is multiplied onto the transmitted waveform. The decaying exponential is biased so that it crosses a threshold at which point the compensating circuitry is turned off.
