罗仁泽 %A 胡进峰 %A 杨晓峰 朱维乐 %J 计算机应用 %D 2007 %I %X A blind least mean square (LMS) scheme was proposed. The new scheme could trace the channel characteristic adaptively through time-variance gain design. And the decision information function in receiver was also adopted to correct the gain. Simulation shows that the new scheme has better performances with high accuracy and fast convergence than that of the LMS method, in terms of different time delay spread, time and signal noise rate (SNR). %K orthogonal frequency division multiplexity (OFDM) %K channel estimation %K blind method
