摘要： Signal decoding apparatus, signal decoding method, program, and information record medium are provided and can accomplish not only high-speed and high-capacity communication, but high-accuracy decoding. An initial channel estimation section 31 estimates an initial channel with a pilot symbol added at the beginning of each packet. After a replica of a transmission symbol is generated, for a reception signal vector, CCI components for L transmission antennas are generated. A CCI canceller 33 removes the CCI components from the reception signal vector. After the reception symbol vector from which the CCI components had been removed has been obtained, a division device 34 obtains an instantaneous estimation value. An update condition determination section 35 detects deterioration of a channel response accuracy based on a threshold value. An instantaneous estimation value whose SNR has been determined to be insufficient is discarded. An averaging circuit 36 outputs a channel response estimation matrix at time t+1 obtained by an averaging process and supplies the matrix to a symbol decoding section 13.

摘要： Communication operations are optimally conducted by applying space-division multiple access in which wireless resources on a spatial axis are shared among a plurality of users.By applying an RD protocol to a communication system that conducts space-division multiple access, spatially multiplexed frames in a TXOP are made more efficient. By specifying a frame length for reverse direction frames with reverse direction permission information and having respective transmitters of reverse direction frames make their frame lengths uniform while respecting the specification, AGC operation stabilizes. Also, a transmit start time for reverse direction frames can be specified by reverse direction permission information, and respective transmitters of reverse direction frames can transmit frames at the same time while respecting the specification.
