摘要： A method and system for receiving and decoding horizontally encoded MIMO-OFDM transmissions with improved efficiency. In one embodiment, MIMO decoding is performed on each of the extracted separate tones of a MIMO-OFDM signal to extract and demodulate frequency domain symbols of the first layer corresponding to one or more code blocks. For each code block of the first layer that passes an error check, corresponding portions of the second layer are decoded using SIMO decoding.

摘要： A device, system, and method are presented for detecting motion. The system may include the device and a first transmitter and a second transmitter configured to transmit a first set of wireless signals and a second set of wireless signals, respectively. The device may have a receiver configured to receive the first and second set of wireless signals, and may further include a processing unit that determines a first value and a second value indicative of fading attenuations experienced by the first set of wireless signals and the second set of wireless signals, respectively. The processing unit may further determine whether the first and second values are each consistent with motion of an object in proximity to the device. The processing unit may cause the device to output an indication of presence of the object if both values are consistent with motion of the object in proximity to the device.

摘要： A system and method for decoding a Multi User (MU) Multiple Input Multiple Output (MIMO) signal is disclosed. The method comprises receiving a selected symbol in a tone of an MU-MIMO signal at a mobile communication device. A channel response for the selected symbol is identified. Spatial whitening is applied to the tone and the channel response using an average of a co-user interference plus noise matrix that is averaged over a selected number of tones. Maximal ratio combining is performed for the spatially whitened tone and the spatially whitened channel response matrix to decode the selected symbol out of the spatially whitened tone.
