TRANSMITTING/RECEIVING APPARATUS METHOD FOR FAST FREQUENCY HOPPING IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEX SYSTEM AND METHOD THEREFOR |
摘要 |
<p>A transmitter and receiver for fast frequency hopping (FFH) of a sample time unit in an orthogonal frequency division multiplexing (OFDM) communication system. The transmitter includes an FFH frequency modulator for converting the data elements of the data vector into a transmission signal vector that hops to a frequency in a sample time unit according to an FFH pattern of the sample time unit. The receiver includes a Fast Fourier Transform (FFF) processor for transforming a received signal vector after frequency hopping into a second received signal vector of a frequency domain by using FFT, a first equalizer for multiplying the received signal vector by an inverse matrix of a channel matrix representing characteristics of a channel from the transmitter to the receiver, and a frequency hopping recovery unit for outputting a recovered received signal vector.</p> |
