[0002] With the popularization and application of smart phones, mobile terminal users have higher and higher requirements for wireless bandwidth, which makes wireless communication put forward higher requirements for optical fiber transmission capabilities, which requires higher-speed radio transceiver equipment, more advanced and reliable Programmable gate array devices (Field-Programmable Gate Array, FPGA) and optical modules with better performance, therefore, lead to a significant increase in equipment costs, and hardware design such as printed circuit board (Printed Circuit Board, PCB) wiring, function Consumption and other greater challenges

[0003] At present, in the existing baseband data transmission system, the compression methods for the transmission data involved mainly include: one method is to group the data first and then compress the data, resulting in a large delay in data compression and decompression processing, thus reducing The range covered by the system signal; moreover, when using FPGA to realize data compression, using a nonlinear compression method such as A-law compression algorithm makes it difficult to implement the device and consumes a large amount of resources, which improves the performance of the device itself. manufacturing cost; another method is to divide the value range after taking the absolute value of the data to be compressed into 2 N Numerical range, if this compression method is applied in the radio frequency coupling remote system, the compressed data bit width sometimes needs 9Bits, at this time, the data division needs to be 256 numerical ranges, which makes the later data processing more complicated and inflexible , and caused a large delay in data signal transmission
