Abstract: Embodiments of this application provide a central unit, a remote unit, a small cell system, and a communication method. A digital-to-analog conversion (DAC) module and an analog-to-digital conversion (ADC) module are disposed in the central unit, so that the central unit transmits an analog optical signal to the remote unit. When the central unit transmits the analog optical signal to a plurality of remote units, because a processing delay of an analog component in analog transmission is usually at a nanosecond level, and a total delay formed by a path transmission delay and the processing delay fluctuates slightly or even is fixed, synchronization of the plurality of remote units can be easily implemented in the central unit through calibration. Therefore, it is possible to easily implement a distributed MIMO function.

Abstract: This application provides encoding and decoding methods to reduce retransmission in satellite communication. A sending apparatus obtains an information transport block, where the information transport block includes a plurality of code blocks; and generates a redundant code block based on at least two of the plurality of code blocks. The at least two code blocks and the redundant code block are sent over a satellite channel after channel coding. A receiving apparatus receives the to-be-decoded information over the satellite channel, calculates, based on the to-be-decoded information of the at least two code blocks and the redundant code block, an a priori log-likelihood ratio of a to-be-decoded bit, and combines the a priori log-likelihood ratio and a log-likelihood ratio obtained after demodulation, to obtain a diversity gain. Decoding is performed based on the combined log-likelihood ratio. This method improves decoding accuracy and reduces the need for retransmission.
