Communication method and apparatus in which transmission control data stored in memory is selected based on a detected signal quality from a decoder

摘要

A communication apparatus for avoiding interference among users of a mobile communication system includes an RF signal processing circuit for processing a received RF signal, an RF demodulating circuit for demodulating an output signal of the RF signal processing circuit, a decoding circuit for decoding an output signal from the RF demodulating circuit, an encoding circuit for encoding a predetermined information signal, an RF modulating circuit for modulating an output signal from the encoding circuit, and a transmission signal processing circuit for processing an output signal from the RF modulating circuit. The encoding circuit includes a memory circuit for storing a predetermined control data, a selecting circuit for selecting the predetermined control data in accordance with an information related to the circuit quality obtained from the decoding circuit, and an adding circuit for adding the transmission data with an output of the selecting circuit. The output power of the transmission signal processing circuit is controlled by the information related to the circuit quality.
