Claim Text:
1. An apparatus comprising: a receiver configured to: a processor coupled to the receiver and configured to: wherein each OFDM RE corresponds to a time-frequency slot that comprises a frequency interval of one OFDM sub-carrier and a time interval of one OFDM symbol, wherein the pilot symbols comprise non-zero transmission energy symbols, and wherein the null symbols comprise zero transmission energy symbols, and wherein the burst marker sequence comprises a pre-determined interlaced pattern between the pilot symbols and the null symbols, wherein the first set of OFDM REs correspond to time-frequency slot positions of the pilot symbols, wherein the second set of OFDM REs correspond to time-frequency slot positions of the null symbols, and wherein computing the power ratio comprises: computing a first total received power for the first set of OFDM REs; computing a second total received power for the second set of OFDM REs; and computing a ratio between the first total received power and the second total received power.
