The Research on the Detection Algorithms for Layered Space-time Codes

LIU Ning,LI Ying,WANG Xin-mei (National Key Lab.of Integrated Services Network,Xidian Univ,Xi'an,Shaanxi 710071,China)  
Layered space-time (LST) architecture is effective in achieving high data rate in wireless communication.Zero-Forcing (ZF) and Minimum Mean-Squared Error (MMSE) algorithms are two common detection algorithms for LST codes.However,both ZF and MMSE require the number of receive antennas to be no less than that of transmit antennas,thus greatly limits the application of LST codes in mobile communication.In this paper we introduce Maximum Likelihood (ML) detection algorithm for LST codes,which has no limit on the number of antennas,and compare the performance of the three detection algorithms for layered space-time codes over flat fading and Rayleigh fading channel.Their applicability is then pointed out respectively.
