摘要:

针对60 GHz脉冲无线通信系统中的多用户干扰问题,研究了基于TH-PAM 的多址调制方案的性能。在IEEE 802.15.3c信道模型下,建立了系统误码性能、通信距离和用户数关系的分析模型,研究了TH-PAM多址调制系统的多用户干扰特性,并与TH-PPM方案进行了比较。仿真结果表明,采用TH-PAM多址调制方式的系统在通信距离小于30 m的范围内,误码率可以保持在10-5以下,而采用TH-PPM方式的系统在100 m的范围内,误码率始终大于10-4。由此可见,TH-PAM比TH-PPM更加适合用于60 GHz短距离无线通信,为5G高频新空口的热点高容量应用场景提供了技术参考。

Abstract:

In view of the multi-user interference problem in 60 GHz pulse wireless communication system,the performance of the system based on TH-PAM multiple modulation scheme was studied. Under the IEEE 802.15.3.c channel model,relationship analysis model between system BER performance,communication distance and number of user was put forward,multi-user interference characteristics of the system with TH-PAM multiple access modulation was studied. It was compared with TH-PPM multiple access system. Simulation results show that the BER of TH-PAM multiple access system can keep below 10-5 within the scope of the communication distance is less than 30 meters,and the BER of TH-PPM multiple access system is always greater than 10-4 in range of 100 meters. As a result,TH-PAM was more suitable for 60 GHz short-range wireless communication than TH-PPM and provided technical reference for hot high capacity scenario of 5G high-frequency new hollow.
