摘要
为了改善脉冲位置调制需要符号同步和数字脉冲间隔调制、双头脉冲间隔调制、多幅度脉冲间隔调制符号长度不固定所引起的接收发机结构复杂和调制器速率不固定等问题，提出将定长数字脉冲间隔调制应用于水下无线光通信系统。分析了带宽需求、传输容量，并与其它调制方式进行了比较; 在给出水下无线光通信信道模型的基础上，推导了该信道中定长数字脉冲间隔调制方式的误包率表达式。结果表明，定长数字脉冲间隔调制适用于水下无线光通信系统。
Abstract
In order to improve the complex structure of the receiver and the transmitter and the unfixed rate of the modulator while pulse position modulation (PPM) needed symbol synchronization and digital pulse interval modulation(DPIM), dual-header pulse interval modulation(DHPIM), multilevel digital pulse interval modulation(MDPIM) had unfixed symbol length, fixed-length digital pulse interval modulation (FDPIM) used in underwater wireless optical communication system was put forward. Bandwidth requirement and transmission capacity were analyzed, compared with on-off keying(OOK), PPM, DPIM and MDPIM. Based on the model of underwater wireless optical communication channel, packet error rate (PER) of FDPIM for this channel was presented. The results show that FDPIM is suitable for underwater optical wireless communication system
