Abstract
Disclosed herein is an interlaced frequency division duplexing method for a duplex communication system. The present invention is constructed to estimate feedback information of a transmission frequency channel using a reception frequency channel. In the interlaced frequency division duplexing method, a frequency band of the duplex communication system is divided into a plurality of frequency channels so as to guarantee similarity between channel characteristics of neighboring frequency channels. Transmission and reception channels are alternately allocated to the plural frequency channels. Accordingly, the present invention can allow a transmitting end of the duplex communication system to easily estimate the variation of feedback information due to the variation of channel characteristics without reducing transmission efficiency under a time-varying multi-path channel environment, and which can prevent the performance of the duplex communication system from being deteriorated due to the variation of channel characteristics.
