| 摘 要： | 对DMR协议的调制解调器进行仿真研究，给出了不同参数对系统功率谱及误码性能的影响曲线。针对最优解调算法实现难度大的问题，提出了一种简化算法，并将其与最优算法进行比较。仿真结果表明，此算法在保证性能的基础上极大地降低了复杂度，提高了可行性。

| Abstract: | Modem of DMR（Digital Mobile Radio） is studied. The system power spectrum and BER（Bit Error Rate） are given during the simulation stage. For demodulation, Viterbi algorithm is optimal. However it is too complex to implementation. In order to overcome this problem, a simplified demodulation algorithm is proposed and the comparison of them is made. Simulation results show that the proposed algorithm can remarkably reduces the complexity and improve the feasibility. |
