Abstract
Official abstract text for this publication.
A communication apparatus, method, and system that reduce adverse effects caused by coupling between a transmission apparatus and a reception apparatus. The transmission apparatus includes a monitoring section that monitors an index value for a total amount of bias of a signal level in signals, a symbol identifying section that identifies a target symbol to be changed in a transmission symbol sequence comprising the signals, based on the index value for the total amount of bias of the signal level, a symbol position changing section that changes a position of the target symbol to a position of a signal point serving to reduce the bias of the signal level, and a transmission section that transmits signals included in the changed transmission symbol sequence to a reception apparatus.
First claim
Opening claim text (preview).
What is claimed is: 1. A transmission apparatus communicatively coupled to a reception apparatus, the transmission apparatus comprising: a monitoring section that monitors an index value for a total amount of bias of a signal level in signals; a symbol identifying section that identifies a target symbol to be changed in a transmission symbol sequence containing the signals, based on the index value for the total amount of bias of the signal level; a symbol position changing se…
