Scalable gain retraining generator, method of gain retraining and multiple-input, multiple-output communications system employing the generator or method |
摘要 |
The present invention provides a gain retraining generator for use with a MIMO transmitter employing N transmit antennas, where N is at least two. In one embodiment, the gain retraining generator includes a first sequence encoder configured to provide a gain retraining sequence to one of the N transmit antennas during a non-initial time interval. The gain retraining generator also includes a second sequence encoder coupled to the first sequence encoder and configured to further provide (N-1) alternative gain retraining sequences to (N-1) remaining transmit antennas, respectively, during the non-initial time interval to retrain receive gains for multiple concurrent data transmissions.
