In order to design a simple and highly accurate channel estimator for wireless personal area network systems, this paper proposes Go lay sequence aided channel estimation. To evaluate the performance of proposed channel estimation, bit error rate performance of single-carrier transmission with frequency-domain equalization has been analyzed by computer simulation. When 8PSK modulation and Reed-Solomon coding RS(255, 239) as forward error correction are used, the proposed Go lay sequence aided channel estimation works very well in millimeter-wave and non line-of-sight fading environments with a 1.8 dB degradation of E(b)/N(0) at 10(-6) of bit error rate against the ideal channel estimation, which is practically acceptable. Moreover, comparing with Chu sequence aided channel estimation, the proposed Go lay sequence aided channel estimation improves 0.4 dB of E(b)/N(0) at the bit error rate while achieving much less hardware than Chu sequence aided one, which is very important for mobile terminal applications.
