摘要： A scrambling initial value is shared without deteriorating transmission efficiency. On the transmission side, a scrambling initial value is created based on a part of a physical layer header not scrambled, a transmission signal sequence scrambled is created by calculating an exclusive-OR operation between a scrambled sequence generated from the scrambling initial value and a transmission data sequence, and is transmitted. On the reception side, the same descrambling initial value as the scrambling initial value is created based on a part of a physical header of a reception frame, and a reception data sequence is descrambled by calculating an exclusive-OR operation between a descrambled sequence generated from this descrambling initial value and a reception signal sequence scrambled.

摘要： Disclosed is a wireless communication apparatus which receives, by multiple antennas, signals created by spatially multiplexing multiple transmit streams subjected to power allocation. The wireless communication apparatus has a channel matrix estimator which estimates a channel matrix of spatially multiplexed channels, a spatial demultiplexer which obtains an antenna receive weight matrix from the estimated channel matrix and demultiplexes into multiple receive streams by multiplying receive signals of antennas by the antenna receive weight matrix, and a power estimator which estimates power allocation information as to each stream. In the wireless communication apparatus, the channel matrix estimator estimates a channel matrix in view of power allocation to each stream estimated by the power estimator.
