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

Abstract

Multi-channel support within single user, multiple user, multiple access, and/or MIMO wireless communications. A communication device is implemented to encode information bit(s) to encoded bits, which subsequently can undergo processing by an interleaver that is implemented to generate interleaved bits. A constellation mapper is implemented to map the interleaved bits to constellation(s) to generate mapped signals. Two or more inverse discrete fast Fourier transform (IDFT) processors are respectively implemented to process the mapped signals to generate signal streams. For example, a first IDFT processor is implemented to process a first of the mapped signals to generate a first signal stream, and a second IDFT processor is implemented to process a second of the mapped signals to generate a second signal stream. Such a communication device also includes communication interface(s) to transmit the signal streams to at least one additional communication device.
