Patent ID: 8130846

Claim:
A method for single carrier space-frequency (SF-SCFDE) transmission over frequency selective and fast fading channel, the method comprising: receiving communication block streams; encoding the received communication block streams to produce communication blocks; compressing the communication blocks to form compressed vectors; repeating the compressed vectors to form vector blocks; phase shifting the vector blocks using a phase shifting matrix to form phase shifted vector blocks, wherein the phase shifting matrix comprises a diagonal matrix that is based at least in part on a number of symbols in at least one of the communication block streams, and wherein the phase shifting matrix is defined φ 4N =diag(1,e j2π/4N , e j2π2/4N , . . . , e j2π(4N-1)/4N ), where N comprises the number of symbols; adding a cyclic prefix to each phase shifted vector block to form transmission blocks; and communicating each transmission block through a frequency selective fading channel.
