Transmission system with interference avoidance capability and method thereof
First Claim
1. A transmission system with interference avoidance capability, comprising:
- a transmission apparatus, comprising;
a first inverse fast Fourier transform unit, receiving input data and transforming the input data to first data;
an interference-processing module, receiving the first data and adding a plurality of extension data to the first data to produce second data for replacing a plurality of data corresponding to an interfered band in the second data with zero data, and producing transmission data;
a transmission-processing module, converting the transmission data to a radio-frequency signal, and transmitting the radio-frequency signal;
a receiving apparatus, comprising;
a receiving-processing module, receiving the radio-frequency signal, and converting the radio-frequency signal to received data;
a removal unit, removing the plurality extension data of the received data, and producing recovered data; and
a first fast Fourier transform unit, transforming the recovered data for producing output data.

Abstract
The present invention relates to a transmission system with interference avoidance capability, which includes a transmission apparatus and a receiving apparatus. The transmission method thereof receives first data by means of an interference-processing module of the transmission apparatus and adds a plurality of extension data to the first data to produce second data for replacing a plurality of data corresponding to an interfered band in the second data with zero data, and then producing transmission data. The transmission data is converted to a radio-frequency signal by a transmission-processing module and transmitted to the receiving apparatus. Thereby, signal interference can be prevented by avoiding spectrum overlap regions.
