摘要： This application presents an adaptive data recovery (ADR) of original data symbols from intervals or parameters of tone signals derived from a received OFDM signal, conducted without compensating distortions or noise introduced to the received OFDM signal by an OFDM transmission channel. Such ADR is implemented by converting back the derived intervals or parameters into original data symbols corresponding to distinctive sets of the intervals or parameters which the derived intervals or parameters belong to.

摘要： Techniques are described for carrier frequency offset (CFO) and channel estimation of orthogonal frequency division multiplexing (OFDM) transmissions over multiple-input multiple-output (MIMO) frequency-selective fading channels. A wireless transmitter forms blocks of symbols by inserting training symbols within two or more blocks of information-bearing symbols. The transmitter applies a hopping code to each of the blocks of symbols to insert a null subcarrier at a different position within each of the blocks of symbols, and a modulator outputs a wireless signal in accordance with the blocks of symbols. A receiver receives the wireless signal and estimates the CFO, and outputs a stream of estimated symbols based on the estimated CFO.

摘要： A wireless communication device includes circuitry and capability to perform carrier frequency offset (CFO) estimation based on signals received from one or more other wireless communication devices. In an orthogonal frequency division multiple access (OFDMA) implementation, the wireless communication device receives two or more OFDMA symbols from first and second other wireless communication devices that include data and a copy/repeat of that data from each of the respective first and second other wireless communication devices within specified one or more sub-carriers. The sub-carrier assignment for the first and second other wireless communication devices is made such that the first wireless communication device transmits first data and the copy of that first data using a first at least one sub-carrier, and the second wireless communication device transmits second data and the copy of that second data using a second at least one sub-carrier.
