Patent Images
1. A communication apparatus for carrying out data communications by allocating data to a plurality of tones, the communication apparatus comprising:
- a bit allocation calculating unit which calculates a number of bits that can be allocated to each tone for each communication apparatus that becomes a communication party, at the time of a training for setting initialization information before carrying out data communications; and
a data communication unit which carries out data communications to each communication apparatus that becomes the communication party based on the bit allocation calculated by the bit allocation calculating unit.

Abstract
A number of bits that can be allocated to each tone is calculated for each communication apparatus, an individual bit allocation is determined for each communication apparatus, and communication apparatuses are managed by being divided into masters and slaves. This makes it possible to secure a transmission rate without requiring labor and cost for the work of installing a blocking filter or the like, and to achieve connection between the low-speed communication apparatus and the high-speed communication apparatus.
