ABSTRACT:
A wireless network (20) participates in radio frequency communication with plural wireless terminals (30). The network (20) comprises plural transmitters (40); a precoder value processor (42) configured to develop a set of precoder values; and a precoder (44) which uses the precoder values for coding the signals transmitted from the plural transmitters. The precoder value processor (42) is configured to develop a set of frequency-independent, linear precoder values for use in precoding signals transmitted from the plural transmitters (30). Each vector of the set is associated with one wireless terminal (30). The set of precoder values is determined such that a set of target average signal to interference noise (SINR) ratios is achieved by the plural wireless terminals with a predetermined total transmit power. Preferably, the predetermined total transmit power is minimum total transmit power.
