摘要 提出了一种利用正交频分复用(OFDM)系统的小区广播信道来进行载波同步的算法,减少了OFDM系统的导频所占用的资源,提高了系统的传输效率.仿真结果表明,该算法在加性高斯白噪声信道以及衰落信道下都具有较好的性能. By making use of the cell broadcast channel, this carrier synchronization technique can reduce the numbers of pilot channel and increase the efficiency of OFDM system. The simulations show that the performance of this technique is good for both the AWGN channel and the fading channel.
