Patent ID: 8401107

Claim:
A transmission method, comprising: encoding a plurality of information bits to generate a plurality of coded bits; scrambling the plurality of coded bits to generate a plurality of scrambled bits; modulating the plurality of scrambled bits to generate a plurality of modulation symbols; mapping the plurality of modulation symbol onto a plurality of subcarriers in at least one transmission layer of a transmission resource; precoding the modulation symbols using a matrix for cyclic delay diversity and a set of codewords from a codebook to generate a plurality of precoded symbols, with a codeword used for precoding modulation symbols corresponding to an i-th subcarrier established by: W ( i )= C k , where C k is a k-th codeword in the set of codewords, with an index k established by: k = mod ⁡ ( [ i q ] - 1 , N ) + 1 , where q is a certain positive integer, and N is the size of the set of codewords; and transmitting the precoded symbols via a plurality of transmission antennas.
