针对传统通信模式易被干扰和保密性差的缺点，设计了一种可以同时传送语音和数据的无线激光通信系统。在保证语音不失真的前提下，采用AMBE语音压缩算法，将语音压缩到4 800 bit/s的数据率，和数据混合编码后驱动激光器发光；接收端接收激光后经光电转换、解码处理将语音和数据还原，通过2.5 km的通信试验，表明该系统具有传输距离远、语音清晰、数据稳定的特点，在未来的空对空、空对地、地对空、地对地通信中将得到广泛的应用。

To overcome the shortcomings of traditional communication systems which were easily disturbed and weakly encrypted，a laser communication system which could transfer audio and data simultaneously was designed. The audio was compressed to 4 800 bit/s data rate without distortion by using the advanced multi-band excitation (AMBE) algorithm, then the coding data stream of audio and data drove the laser to emit. Audio and data were recovered after electro-optical conversion and decoding at the receiver. The communication experiment with the distance of 2.5km proves that the system features long distance, clear audio and stable data, it can be applied in air-to-air, air-to-ground, ground-to-air and ground -to-ground communications.
