摘要： A transmitter and receiver for fast frequency hopping based on a cyclic frequency hopping pattern in an orthogonal frequency division multiplexing system. The transmitter outputs a transmission signal vector having a plurality of samples. In the receiver, a first Fast Fourier Transform (FFT) processor transforms a first received signal vector into a second received signal vector of a frequency domain by using FFT. An equalizer multiplies the received signal vector by an inverse matrix of a channel matrix representing characteristics of a channel from the transmitter to the receiver. A modified IFFT processor transforms output of the equalizer by using IFFT, and multiplies IFFT outputs of a last stage of the modified IFFT processor by predetermined gains associated with the cyclic frequency hopping pattern of the transmitter. A second FFT processor transforms output of the modified IFFT processor by using FFT to output a recovered received signal vector.

摘要： A transmission/reception method and apparatus in an Orthogonal Frequency Division Multiplexing (OFDM)-based wireless communication system are provided, in which a data transmitter adaptively selects a multiplexing scheme according to a code rate of the transmission packet or an effective SNR of a wireless channel for a corresponding terminal, when transmitting a packet data channel. The adaptive multiplexing scheme is equal in concept to a scheme of adaptively implementing unitary precoding. The unitary precoded multiplexing includes Orthogonal Frequency code Domain Multiplexing (OFCDM), Fast Fourier Transform-Spread-OFDM (FFT-S-OFDM), Fast Frequency Hopping-OFDM (FFH-OFDM), and the like. The method and apparatus adaptively selects the multiplexing scheme and transmits/receives data using the selected multiplexing scheme, thereby improving reception performance of the packet data.
