摘要
探讨了OFDM技术与通信系统之间存在的资源优化配置关系．OFDM技术原理以及优越性,它频谱利用率高、抗码问干扰能力强,实现了同时满足高速传输和降低干扰的两方面要求,极大地简化了通信系统的复杂性．
This paper discusses the resource disposition relationships between the OFDM technique and communication systems, the principle of OFDM technique and advantages. This paper presets that the benefits of OFDM are high spectral efficiency and resiliency to code interference, it can meet the requirements for both high speed transmission and low interference, and can reduce the complexity of the communications systems.
