摘　　要：针对信号检测结果信噪比较低,难以应对恶劣条件的问题,为了减少点对点电力能源交易系统终端多用户信号检测的时间,研究了一种新的多用户信号盲检测算法。利用信号盲检测方法,通过软件无线电内部的智能化盲接收机,进行多用户信号处理,完整监视与捕捉终端系统传输的信号数据,同时加强数据间的联系,构建一体化检测处理空间,执行信号盲检测算法的计算指令。选取适宜的信号特征集,根据信号归类的方式,划分不同的系统终端信号数据,提取信号因子之间的关联参数,分配信号传输的关键因子,完成信号盲检测算法设计。实验结果表明,该算法在盲检过程中花费的时间最短,且始终低于3 s;在低信噪比的恶劣条件下显示出极好的性能。Aiming at the problem that the signal-to-noise ratio of signal detection results is low and it is difficult to deal with bad conditions,a new multi-user signal blind detection algorithm is studied in order to reduce the terminal multi-user signal detection time of peer-to-peer power energy trading system.Using the signal blind detection method,through the internal intelligent blind receiver of software radio,carry out multi-user signal processing,completely monitor and capture the signal data transmitted by the terminal system,strengthen the connection between the data,build an integrated detection and processing space,and execute the calculation instruction of signal blind detection calculation method.Select the appropriate signal feature set,divide the signal data of different system terminals according to the way of signal classification,extract the correlation parameters between signal factors,allocate the key factors of signal transmission,and complete the design of signal blind detection algorithm.The experimental results show that the algorithm spends the shortest time in the blind detection process,and is always less than 3 s.It shows excellent performance under poor conditions with low signal-to-noise ratio.
