Abstract: A method of data transmission includes: receiving a first packet, where the first packet includes first compressed data and a first check value, the first compressed data is obtained by compressing first data based on a first compression mode, the first check value is obtained by processing a second check value based on a first check algorithm, the second check value is obtained by processing the first compressed data based on a second check algorithm; obtaining a first check code by processing the first packet based on a third check algorithm; determining, according to a correspondence between the first check code and the first compression mode, that the first compression mode is a compression mode used when the first data is compressed; and obtaining the first data by decompressing, based on a first decompression mode corresponding to the first compression mode, the first compressed data included in the first packet.

Abstract: A microwave transmission apparatus is provided. A multiplexing unit generates multiplexed data based on a service clock rate. An interface unit writes and reads the multiplexed data at the service clock rate and a read clock rate respectively. An encoding and mapping unit performs encoding and mapping on the multiplexed data using a symbol clock rate to generate symbol data, and sends the symbol data to up conversion units. A clock tracking unit generates the symbol clock according to the system clock, and performs frequency division on the symbol clock to acquire the read clock. A stream control unit adjusts the service clock rate according to a water line error generated by the interface unit, so that the service clock rate is equal to the read clock rate. As a frequency and a phase of the system clock are fixed, even ACM switching occurs, the system clock is stably transferred.
