Variable Step-Size Multi-Modulus Algorithm with Quantized Error Method

摘要：

In this paper, we propose a variable stepsize multimodulus algorithm with quantized-error method (QEVSSMMA), which benefits from a nonlinear quantized error method as well as the variable stepsize method and thus holds reduced computational complexity and improved convergence rate compared to conventional multi-modulus algorithm (MMA). Simulation shows that the new algorithm has the characteristics of faster convergence, lower implementation cost while preserves the robustness property and the phase recovery functionality of MMA. The new algorithm is suitable for resource-limited environment
