Title:
タイムスロットCDMAシステムにおける多コード集合通信路推定方法
Document Type and Number:
Japanese Patent JP4724225
Kind Code:
B2
Abstract:
A multiple code-set channel estimation method in time-slot CDMA system, includes the step of: A, performing a single code-set channel estimation for each code-set signal, respectively, to obtain an channel estimation result; B, extracting the maximum interference tap from said result of channel estimation; C, resuming the interference component caused by the response of the maximum interfere tap to each code-set signal, and obtaining the channel estimation result of clean signal of each code-set; E, deciding whether the number of interaction are reached, if so, outputting the channel estimation result of each single code-set, otherwise, making the channel estimation result of clean signal of each code-set as the channel estimation result of the code-set to be processed at nest step, and returning to the step B. By use of the present invention, the multiple code-set union channel estimation can be implemented simply and effectively.
