Claim 13:
14. The apparatus of claim 12, wherein the instructions, when executed with the at least one processor, cause the apparatus to perform computing the precoder for the subcarriers in the set of subcarriers successively in order of increasing or decreasing subcarrier index, wherein the set of power allocation weights of the access point antennas for subcarrier index l is wn(l) and initialising the set of power allocation weights of the access point antennas for subcarrier index l to w0(l)=wn(l−1) when successively computing precoders for increasing subcarrier index or to w0(l)=wn(l+1) when successively computing precoders for decreasing subcarrier index.
