摘要
根据最小均方误差原理,对数字通信系统中获得码元同步的信号提出了一种新的码元判决算法,给出了在某无线通信设备中的应用结果。此算法在信噪比很低的情况下,都能很好地还原出原数字信号,具有高保真与强抗噪性能,且运算量小,易于高速单片机及DSP实现,适合软件无线电技术的应用。
This paper, based on MSE principle, presents a new code judgment algorithm, which aims at the code synchronization signal obtained in digital communication system. It also gives the application results in certain wireless communication device. This algorithm could truly detect digital signal in low SNR condition, and is of high fidelity and strong noise-resistant robustness. It could be easily implemented with high speed MCU and DSP and is of less calculation. This algorithm is quite applicable in software radio technology.
