Multi-channel support within single user, multiple user, multiple access, and/or MIMO wireless communications

摘要

Multi-channel support within single user, multiple user, multiple access, and/or MIMO wireless communications. A processor of the communication device is implemented to process a signal to generate processed signals. Also, the communication device includes multiple inverse discrete fast Fourier transform (IDFT) processors respectively to process the processed signals to generate a signal streams respectively across channels (e.g., a first of the IDFT processors is implemented to process a first processed signal to generate a first signal stream based on a fast Fourier transform (FFT) channelization across a first number of orthogonal frequency division multiplexing (OFDM) tones, and a second of the IDFT processors is implemented to process a second processed signal to generate a second signal stream based on the FFT channelization across a second number of OFDM tones). The communication device also includes communication interface(s) to transmit the signal streams to at least one additional communication device.
