摘要：
This paper presents two novel channel estimation algorithms for block transmission systems with two transmit antennas over frequency-selective fading channels: Time-Domain-Processing-Based Algorithm (TDPBA) and Frequency-Domain-Processing-Based Algorithm (FDPBA). Performance analysis of the two novel algorithms and simulation results show that both can achieve good channel estimation performance at low and middle Signal-to-Noise Power Ratios (SNRs), but TDPBA's computational complexity is lower than that of FDPBA, while the "flat-roof effect" which appears in TDPBA at high SNRs can be avoided in FDPBA.
