54102 窄带干扰(Narrowband Interference,NBI),作为一种敌意的频域干扰,会严重地恶化最小频移键控(Minimum Shift Keying,MSK)非相干检测的误码率(Bit Error Rate,BER)性能。 Narrowband interference(NBI), as kind of hostile frequency-domain interference, can seriously impair the bit error rate(BER) performance of minimum shift keying(MSK) noncoherent detection.
54103 为降低窄带干扰对BER性能的影响,MSK非相干接收机一般首先对接收信号进行干扰抑制。 To reduce the impact of narrowband interference on BER performance, MSK noncoherent receivers generally first perform interference suppression on received signals.
54104 然而现有MSK非相干检测算法并未考虑干扰抑制对MSK信号造成的畸变,这制约了窄带干扰下非相干检测的MSK通信系统的BER性能。 However, existing MSK noncoherent detection algorithms do not consider the distortion of MSK signals caused by interference suppression, which limits the BER performance of the MSK communication system with noncoherent detection under narrowband interference.
54105 为了解决这个问题,本文提出了一种基于深度学习的MSK非相干接收机(Deep Learning-Based MSK Noncoherent Receiver,DL-MSKNCR)。 In order to solve this problem, a deep learning-based MSK noncoherent receiver(DL-MSKNCR) is proposed in this paper.
54106 该接收机包含一个干扰抑制子网络和一个MSK非相干检测子网络。 This receiver contains an interference suppression subnetwork and an MSK noncoherent detection subnetwork.
