Receiving apparatus, method for receiving, and wireless communication system

摘要

A receiving apparatus includes an estimator that estimates a channel of a known signal received in the receiving apparatus, and a controller that controls a weight value based on the result of the estimating, the weight value being to be multiplied by a replica signal of the known signal.

1. A receiving apparatus comprising:
an estimator that estimates a channel of a known signal received in the receiving apparatus; a controller that controls a weight value based on the result of the estimating, the weight value being multiplied by a replica signal of the known signal, the replica signal being obtained by multiplying the estimated channel of the known signal by the known signal, the weight value g being expressed byg=11+E⁢{m2}/(he2-E⁢{m2}), where m represents an estimation error of the channel, he represents the estimated channel, and E{X} represents an average of variable X; and a processor that processes a received desired signal by subtracting the product of the weight value and the replica signal from the received desired signal.
