A channel-estimation-based equalization algorithm for fast frequency hopping radio

This paper presents a channel estimation based equalization algorithm for high speed fast hopping radio. The equalizer coefficients are directly calculated from the impulse response of the channel which is obtained by rapid channel estimation in time domain employing cyclically extended binary sequence. Simulation is done under general two-path channel model and rapidly fading channels. Theoretical analysis and computer simulation results show that compared with traditional adaptive coefficients adjusting equalizer or MLSE receiver, this algorithm is more robust and has less computational overhead, which is desirable under limited time resources.
