Abstract: A light transmitter to transmit multiple light packets, each formatted to include a same message comprising a series of bits, each bit represented as light that is intensity modulated over a bit period at a frequency indicative of the bit. The light packets are transmitted at different start-times to establish different phases, one for each of the light packets, to permit a light receiver to sample each message at a different phase of a fixed sample timeline that is asynchronous to the bit period and the frequency. The light receiver samples the multiple light packets based on the sample timeline, to sample each received message at one of the different sample phases, then constructs a best series of bits based on the multiple demodulated messages.

Abstract translation: 一种光发射机，用于传输多个光分组，每个光分组被格式化以包括包括一系列比特的相同消息，每个比特被表示为在表示该比特的频率的比特周期上进行强度调制的光。 光分组在不同的启动时间被发送以建立不同的相位，每个光分组一个，以允许光接收机在与比特周期异步的固定采样时间线的不同阶段采样每个消息，并且 频率。 光接收机基于采样时间线对多个光分组进行采样，以在不同采样阶段之一对每个接收到的消息进行采样，然后基于多个解调消息构建最佳的一系列位。
