Application of Frequency-Domain Iterative Block Decision-feedback Equalizer in HF Communication
摘要
Abstract
The principle of frequency⁃domain iterative block decision⁃feedback equalizer is studied.The algorithm diagram is pres⁃ented and the calculation formulas of feed⁃forward and feed⁃back coefficients are given. To analysis the performance of this algorithm, simulation of its application in short frame HF communication is carried out.Experiment results show that when choosing fitting training sequence likes CAZAC,frequency⁃domain iterative block decision⁃feedback equalizer can achieve similar performance as time⁃domain equalizer with significant reduction of computing complexity.关键词
