摘要
对于多径环境下TDMA信号的码间干扰 (ISI)和共道干扰 (ICI) ,利用了TDMA信号的恒模特性进行盲空时处理 ,并提出一种改进的空时处理算法。该算法克服了空时恒模算法不能有效工作在多径环境下的信号处理的缺点。
Blind space time process of TDMA is researched to eliminate the inter symbol interfere and co channel interfere under the condition of multi path. And a improved space time algorithm is proposed. The new algorithm overcomes the shortcoming of CM algorithm that works badly under the multi path circumstance. Computer simulations are provided to illustrate the performance of the method proposed.
