Abstract
Calibration methods and structures are provided for wireless communications devices that compensate across a signal bandwidth for relative gain and phase errors between spatial communication channels while utilizing existing transceiver structures and facilitating the use of frequency-domain spatial processing. The methods and structures are directed to time-division duplex (TDD) systems, and are particularly suited to those that incorporate orthogonal frequency division multiplexing (OFDM).
