Scalable data reception gain control for a multiple-input, multiple-output (MIMO) communications system |
摘要 |
The present invention provides a concurrent gain generator for use with a MIMO transmitter having an N of two or more transmit antennas. In one embodiment, the concurrent gain generator includes a first sequence formatter that provides one of the N transmit antennas with a gain training sequence during an initial time interval, and a second sequence formatter that further provides (N-1) remaining transmit antennas with (N-1) additional gain training sequences during the initial time interval to train receive gains. The present invention also provides a non-concurrent gain adjuster for use with a MIMO receiver employing an M of two or more receive antennas. In one embodiment, the non-concurrent gain adjuster includes a gain combiner that computes a common receive gain as a function of M independent receive gains, and a gain applier that applies the common receive gain to receivers associated with the M receive antennas.
