为了设计一种简单、高精度的无线个域网信道估计器，本文提出了格雷序列辅助的信道估计器。为了评估所提出的信道估计方法的性能，通过计算机仿真分析了频域均衡的单载波传输的误码率性能。当使用8PSK调制和RS(255,239)编码作为前向纠错时，本文提出的格雷序列辅助的信道估计在毫米波和非视距衰落环境中具有很好的性能，在误码率为10-6时，Eb/N0比理想的信道估计有1.8dB的下降，这在实际中是可以接受的。此外，与Chu序列辅助的信道估计相比，本文提出的Golay序列辅助的信道估计在误码率下提高了0.4dBEB/N0，而硬件实现却比Chu序列辅助的小得多，这对于移动终端的应用是非常重要的。
In order to design a simple and highly accurate channel estimator for wireless personal area network systems, this paper proposes Golay 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 Golay sequence aided channel estimation works very well in millimeter-wave and non line-of-sight fading environments with a 1.8 dB degradation of Eb/N0 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 Golay sequence aided channel estimation improves 0.4 dB of Eb/N0 at the bit error rate while achieving much less hardware than Chu sequence aided one, which is very important for mobile terminal applications.
