摘要
针对通信系统中信号容易被周围噪声污染的问题,提出了一种基于DSP强抗干扰无线通信。发送端信号经DSP处理后送入无线信道,接收端语音信号经DSP处理后得到原始语音信号。在语音处理时添加了抗噪声处理,压缩编解码和纠错编解码。极大地提高了抗噪声和自我修复能力。可用于不同场合的保密通信领域。
According to the problem that the signal in the communication system is easy to be contaminated by the noise around, a new strong anti-jamming wireless communication based on DSP has been developed. The signal sent by the sender issent to the wireless channel after disposed by the DSP, original speech coding can be got after the signal received by the reception was disposed by the DSP. Anti-noise disposal, compression coding and decoding, error correction coding and decoding are appended during audio processing. Thus anti-noise and self-repair ability are greatly improved. It can be used for different communication secrety.
