摘要
Turbo迭代均衡技术与OFDM相结合能够有效提高系统的抗干扰、抗衰落性能,从而提高系统的通信质量和容量。以往的研究大多是从Turbo均衡的算法的角度上进行研究和改进,本文以OFDM系统的Turbo均衡链路为基础,从工程实现的角度对系统实现的整体架构进行改进,并在TI C6416T DSP上进行了仿真验证。仿真结果表明,本文提出的Turbo均衡链路的实现方式能有效提高系统的实现性能,增加Turbo迭代的次数和效果。
The combination of Turbo equalization and OFDM can enhance the anti-jamming, anti-fading performance of the system and improve the communication quality and capacity efficiently. Most previous studies make the improvement through the algorithm of Turbo equalization. However, based on the Turbo equalization link of OFDM system, this paper makes the improvement of systematic entirety structure from engineering implementation＇ s point of view, which has been proved by simulation on TI C6416T DSP. The simulation results show that the implementation of Turbo equalization link proposed by this paper can improve the performance of system effectively and increase the iterative times of Turbo equalization.
