A new robust chip equalization algorithm

码片均衡是提高第三代移动通信系统性能的关键技术之一。为了增强码片均衡器抗突发干扰的能力,本文将应用数学中的“稳健估计(RE)”应用于MRLS算法中,得到稳健的MRLS算法(RMRLS)。理论分析与计算机模拟结果都证明了RMRLS算法在保持MRLS算法的优点的同时,提高其抗突发干扰的能力,使MRLS算法更加稳健。

Chip equalization is one of the key technologies for improving 3G mobile communications’ performance. In order to enhance the robustness of the chip equalizer, the robust estimation method is applied to MRLS algorithm, resulting in a new robust MRLS algorithm (RMRLS). Theoretical analysis and simulation results show that the proposed RMRLS keeps the advantage of MRLS and has better anti-jamming performance than the latter.
