Transmitting apparatus, receiving apparatus, and communication system for formatting data
First Claim
1. A transmitting apparatus in an orthogonal frequency division multiplexing (OFDM) wireless communication system, comprising:
- a transmission processing unit configured to transmit at least one transmission OFDM signal in a transmission period among a series of transmission periods, each transmission period including a guard interval;
wherein the at least one transmission OFDM signal includes, in addition to the guard interval included in each transmission period, a no transmission signal period whose length is less than a length of the series of transmission periods, the no transmission signal period following after the series of transmission periods during a time period different from that of the guard interval.

Abstract
A transmitting apparatus, a receiving apparatus, and a communication system are provided that allow a reduction in a frame loss due to interference caused by use of the same channel. A transmitting apparatus disposed in a base station includes a GPS receiver for receiving a GPS signal, a timing generator for controlling respective function blocks in accordance with the GPS signal and an inter-base-station control signal so as to precisely synchronize the timing of frame transmission among base stations, the front-end transmission processing unit including for converting transmission information into transmission time slots, a frame generator for generating a frame including a plurality of time slots and one frame guard, and a back-end transmission processing unit for transmitting the generated frame as a radio signal.
