Performance of a CDMA system employing AMC and multicodes in the presence of channel estimation errors
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2008年 第2期56卷 189-193页
作者: Kwan, Raymond Leung, Cyril Univ British Columbia Dept Elect & Comp Engn Vancouver BC V6T 1Z4 Canada
The impact of channel state estimation errors in a CDMA system employing adaptive modulation and coding in conjunction with multicodes is studied. The channel is modelled as a finite-state Markov chain and the perform... 详细信息
