Patent ID: 8428170

Claim:
A method for transmitting symbols in a communication system, the method comprising: dividing N symbols to be transmitted at substantially the same time into a first group and a second group, performing a first processing on each of a plurality of symbols in the first group to obtain a first group of superimposed symbols, and performing a second processing on each of a plurality of symbols in the second group to obtain a second group of superimposed symbols; and transmitting each of the first group of superimposed symbols by a first antenna, and transmitting corresponding symbols in the second group of superimposed symbols by a second antenna, wherein the first processing and the second processing respectively include a conjugate cancellation operation, wherein the conjugate cancelation operation includes a weighted operation and a conjugate operation, and wherein when N equals 8, the symbols transmitted by the first antenna at Timing i+2, i+1 and i are: cs3+ds4, as1+bs2+cs3+ds4 and −(e*s5*+f*s6*+g*s7*+h*s8*) respectively, where a, b, c, d, e, f, g and h are respectively complex constants, “*” indicates the conjugate operation, and s1 to s8 are respectively serial numbers of the symbols to be transmitted.
