Abstract

The invention provides a low code rate encoding method, device and storage medium for short frame bursts. The method includes: obtaining multiple channels of interleaved information bits of original information bits, inputting each channel of interleaved information bits into a corresponding component encoder, and outputting each channel of tail-biting convolutional coding symbols; Perform Hadamard encoding on the interleaving information bits and the tail-biting convolutional encoding symbols to obtain the encoding symbols of each component encoder; perform a parallel-to-serial conversion operation on the encoding symbols of the component encoders output by each path and the original information bits to obtain Hadamard‑Turbo concatenated encoding symbols. The present invention realizes high-gain low code rate coding without loss of coding efficiency by concatenating Hadamard coding and tail-biting convolution coding symbols, and reduces decoding complexity.

Description

technical field [0001] The present invention relates to the technical field of digital signal processing, in particular to a low bit rate encoding method, device and storage medium for short frame bursts. Background technique [0002] Tactical ad-hoc network is an important means of communication support for future wars. It has the characteristics of flexibility, easy deployment, and swarm intelligence. However, it must also overcome the adverse effects of high dynamics, large fading, and strong interference. As the number of access equipment and the demand for communication rates continue to grow, intersymbol interference caused by interfering signals in the frequency band and multipath effects will seriously affect communication quality, while traditional time division multiple access and frequency division multiple access Access and other methods are not effective in anti-interference and resistance to fading. [0003] The frequency hopping communication system reduces t...
