Abstract:
1. A receiving apparatus comprising: a receiving section that receives a signal comprised of streams which are spatially multiplexed; a spatial demultiplexing capacity estimating section that estimates a capacity for demultiplexing the signal into the streams by detecting an error of the signal and obtaining an error rate for each of a plurality of multiplexing numbers, each multiplexing number being a number of the streams that are spatially multiplexed; an offset setting section that sets an offset value for each of the multiplexing numbers, respectively, based on the obtained error rate using a predetermined association between the obtained error rate and the offset value, the offset values being used for controlling a first multiplexing number from among the multiplexing numbers; a received quality measuring section that measures received quality of each of the streams; and a feedback section that feeds back, to a transmitting apparatus, information indicating each of the offset values and the received quality.
