Abstract:
1. A method for receiving a first chip-block and a second chip-block over a single-carrier communication channel with a receiver that is coupled to a receiver antenna, the first chip-block transmitted from a transmitter coupled to a first antenna, the second chip-block transmitted from the transmitter coupled to a second antenna, the method comprising: receiving over the single-carrier communication channel the first chip-block and the second chip-block, wherein the first chip-block and the second chip-block separately include a first block of symbols and a second block of symbols that have been spread based, at least in part on a first orthogonal spreading code and a second orthogonal spreading code and then combined for transmission by superimposing and/or interleaving the first block of symbols with the second block of symbols; generating a first received chip vector from the first chip-block and a second received chip vector from the second chip-block; de-spreading the first chip-block and the second chip-block included in the first and the second received chip vectors, the de-spreading to occur in the frequency domain; and generating an estimate of data associated with a symbol included in the first and second block of symbols, the estimate to occur in the time domain.
