摘　　要：CMMB系统使用发射机标识序列标识不同的发射机。通过分析这些随机序列之间的关系,提出了一种基于Hadamard矩阵的产生和检测方法,并在Altera公司的EP3C55FPGA上实现。实验结果表明,该方法速度快,且省去了传统查表法所需的存储器消耗。Transmitter ID sequences are used to distinguish CMMB transmitters in different regions. By analyzing the relationship of the random sequences, a method based on Hadamard matrix is proposed to generate and detect CMMB transmitter ID sequences. The proposed method is implemented on Ahera EP3C55 FPGA. Experimental results show that the proposed method runs fast, and requires no longer memory consumption under the conventional lookup table method.
