Abstract:
1. In a wireless communication system, a method for receiving a signal, said method comprising: receiving a first OFDM signal via a first antenna element; receiving a second OFDM signal via a second antenna element; during a first channel training period, within each of a plurality of frequency subchannels, obtaining received signal measurements via said first antenna element and via said second antenna element; during a second channel training period, within each of a plurality of frequency subchannels, obtaining received signal measurements via said first antenna element and via said second antenna element; and measuring a MIMO channel response based on said measurements made during said first channel training period and said second channel training period; wherein a first transmitting antenna element is quiet during a portion of said first and second channel training periods and a second transmitting antenna element is quiet during another portion of said first and second channel training periods.
