摘要

本文研究了适用于回波抵消应用的计算效率高的自适应算法。在选择性偏系数更新算法(SPCUA)中增加了误差和/或回归向量的2次幂(PO2)量化，以进一步减少计算量。为了在生成的误差值低于某一限度时节省更多的计算，文中还包含了一个简单的走走停停过程。仿真结果表明了改进算法的优越性

On computationally-efficient NLMS-based algorithms for echo cancellation applications

This paper investigates computationally-efficient adaptive algorithms suitable for echo cancellation applications. Power-of-two (PO2) quantization for the error and/or regressor vector is added to a selective-partial-coefficient-update algorithm (SPCUA) to further reduce the amount of computations. A simple stop-and-go procedure is included to save more computations when the generated error magnitude is below a certain limit. Simulation results with comparisons are included to show the advantages of the improved algorithms
