Claim:
1. A method of operating a wireless multiple input multiple output (MIMO) device capable of wirelessly receiving and transmitting a plurality of data streams, the method comprising: receiving pilot or reference signals from a second wireless MIMO device for a plurality of communication channels, wherein the data streams are transmitted through the communication channels, respectively; estimating the communication channels, using the reference signals or the pilot signals; and determining, based on the estimated communication channels, pairs of an analogue digital converter (ADC) quantizer and an input distribution for each of the data streams, wherein the input distribution is a probability measure of channel input data, and is determined based on the estimated communication channels, wherein the pairs of an ADC quantizer and an input distribution for each of the data streams are optimized to maximize a throughput in each of the estimated communication channels.
