OFDM TRANSMITTING APPARATUS, OFDM RECEIVING APPARATUS, AND THEIR METHODS

摘要

An OFDM transmitting apparatus capable of preventing any degradation of the throughput of the communication system without assigning any resources of the communication system for transmission of a control channel. In the apparatus, a switch (121) selectively supplies, based on the encoded data of the control channel outputted from an encoding part (110), a plurality of outputs from a repetition part (103) to pattern generating parts (122-1 to 122-2). In this way, a plurality of types of repetition patterns can be used to generate outbound data. An assigning part (123) maps the outbound data generated by one of the pattern generating parts to a subcarrier.
