Abstract

The invention discloses a simplex asynchronous Manchester code receiving and decoding method, relates to the communication field, and improves the shortcomings of the existing simplex asynchronous Manchester code receiving and processing method. The present invention expands the hardware platform adapted to the original asynchronous Manchester code, changes the original C language code into hardware language code, and expands from being applicable to MCU type chips to FPGA type chips; the present invention can receive multiple channels on an FPGA chip The asynchronous Manchester code data stream has the characteristics of concurrency, real-time, single-line, and high speed; the invention only needs a small scale of software and hardware to achieve better error detection and tolerance effects, and achieves a better balance between complexity and performance. In the reception and decoding of asynchronous Manchester codes.

Description

technical field [0001] The invention relates to the communication field, in particular to a simplex asynchronous Manchester code receiving and decoding method. Background technique [0002] Asynchronous Manchester code is a communication coding method that uses phase coding. It determines whether the transmitted symbol is 0 or 1 through the duration of high and low levels and the contextual relationship within a symbol period. During synchronous transmission, the sending end should send out the data signal and the symbol clock signal at the same time, and the receiving end uses the received clock signal to sample the received data and restore the symbol data. During asynchronous transmission, the sending end only sends the symbol signal and does not send the clock signal. Generally, the synchronization header is sent before the symbol data. The receiving end regenerates the local clock according to the received synchronization header, and the local clock samples and recovers...
