Data transmission rate control using a transmission control scheme suitable for a subband

摘要

A data transmission rate control method in which a transmission control scheme used for data transmission over each channel is switched depending on a subband to which a proper transmission rate of the channel belongs, the subband being prepared by dividing an entire band by one or more boundaries. This makes it possible to solve a problem involved in a conventional systems of variations in accuracy due to the bandwidth, and an increase in the circuit scale, when the a cell rate to be controlled ranges over wide bandwidth.
