Claim:
1. A method comprising: generating estimates of channel characteristics of channels between a receiver that uses M receiver antennas and K synchronized terminal units that each transmit on N antennas, the receiver including a processor and a memory configured to store at least one corresponding sequence of instructions executable on the processor; and estimating symbols that were transmitted by a corresponding terminal unit of the K synchronized terminal units, the estimating being based on the estimates of channel characteristics, the symbols being estimated by suppressing signals from all but the corresponding terminal unit, where K, M, and N, are integers, 2≦K≦M, and N>1, wherein the generating and the estimating include executing at least one sequence of instructions on the processor, and wherein the symbols are estimated based on maximum likelihood decoding and one of zero forcing interference cancellation and minimum mean-squared error interference cancellation.
