Quantized CMA equalization for shaped signal constellations
收藏 引用
IEEE SIGNAL PROCESSING LETTERS 2004年 第2期11卷 67-70页
作者: Athuraliya, SA Garth, LM Univ Canterbury Dept Elect & Comp Engn Christchurch 1 New Zealand
Constellation shaping introduced to maximize channel capacity is detrimental to the performance of many cost function-based blind equalization algorithms including the constant modulus algorithm (CMA). We propose a ne... 详细信息

CHINESE JOURNAL OF ELECTRONICS 2000年 第2期9卷 163-165页
作者: Wang, Y Zhao, JP Wu, WL Beijing Univ Posts & Telecommun Beijing 100876 Peoples R China
constant modulus algorithm (CMA) for blind multiuser detection is proposed in [3]. However, the first type of stationary points in [3] is not correct. A general expression for the solutions is given in this paper, whi... 详细信息

IEEE TRANSACTIONS ON SIGNAL PROCESSING 2000年 第5期48卷 1503-1506页
作者: Jani, UG Dowling, EM Golden, RM Wang, ZF Univ Texas Erik Jonsson Sch Engn & Comp Sci Richardson TX 75083 USA
In this correspondence, we extend the results from Wang and Dowling to provide a low-cost and high performance blind adaptive interference suppression scheme for CDMA systems. Simulation results confirm that the propo... 详细信息

SIGNAL PROCESSING 2002年 第11期82卷 1675-1693页
作者: Szczecinski, LL Gei, A INRS Energy Mat & Telecommun Montreal PQ H5A 1C6 Canada Univ Chile Dept Elect Engn Santiago Chile
Decision feedback equalisers offer a good compromise between complexity and performance for channels with strong intersymbol interference. However, their blind or decision-directed adaptation may converge to degenerat... 详细信息
