摘要
本文给出了一个快速高效且易于实现的信道响应估计算法。对本算法的一系列仿真,将证明基于该算法的自适应均衡具有低SNR门限,能对付大幅度(包括0dB的付径)付径的特点。由于该算法占用的硬件资源很少,尤其适用于数字电视地面广播中的VSB(残留边带调制)接收机。
A simple, fast and efficient channel estimate algorithm is proposed. Simulation results prove that the proposed algorithm can combat with multi-path interference of 0dB magnitude without degradation caused by Additive White Guassian Noise (AWGN). Hardware complexity can be reduced, the proposed algorithm is perspective to be used for VSB-receiver in digital television terrestrial broadcasting (DTTB).
