4433 对 16QAM-LFM 这一新型一体化波形的性能分析和计算机仿真表明，在通信性能方面，该波形与 16QAM 信号的通信误码率特性相同，具有比 BPSK-LFM、MSK-LFM 等低阶调制的一体化信号更高的频带利用率，比 OFDM-LFM 等高效率一体化信号更低的复杂度； The analysis and computer simulation for the 16QAM-LFMwaveform show that the new waveform has the same bit error rate as the classic 16QAM signal and larger spectrum effi-ciency compared with the integrated waveforms such as BPSK-LFM and MSK-LFM. Furthermore, the computationalcomplexity of 16QAM-LFM is less than the existing OFDM-LFM waveform. On the other hand, 16QAM-LFM hashigher distance resolution and speed resolution than the traditional LFM pulse signal since its ambiguity function lookslike a thumb tack.
4434 在雷达性能方面，该波形因为其雷达模糊函数接近图钉型，具有比 LFM 信号更高的距离和速度分辨力，对低速目标的检测概率则相同。 And the detection probability of radar is similar as traditional LFM pulse signal for the slowly moving object.
4435 针对经典保密通信中信息安全传输的问题，提出了一种基于循环码和信息压缩的量子保密通信算法。 For the problem that the classical secure communication was challenging to transmit information, a quantumsecure communication algorithm based on cyclic code and information compression was proposed.
4436 首先，发送端对传输的信息进行预处理，将其分割为长度不等的 2 组数据，分别用于循环编码和压缩编码。 First, the data wasencoded into two sets of data with different lengths by the sender, one set of data was used for cycling coding and theother one was used to compress coding.
4437 然后，发送端添加一串量子态传输至接收端，采用误码数作为信道安全检测的依据， Second, single-photon sequence was transmitted to the receiver on the quantumchannel by the sender. The error number was used as the basis of channel security detection.
4438 若信道安全，则对预处理后的数据量子态处理，利用量子稳定子码编码分段并传输，依据稳定字码的特性克服环境引起的误码。 If the channel was secure,quantum states were encoded for the data, and segment transmitted by quantum stabilizer codes. The error caused by theenvironment can be overcome according to characteristic of the stable code.
4439 最后，接收端接收到量子信息后进行解码，并解循环和解压缩从而获得数据。 Finally, the information was decoded afterreceiving the quantum information, then recirculated and decompressed to obtain data.
