Convolutional Coding Data Transmission System Using Real-Valued Self-Orthogonal Finite-Length Sequences

摘要

A real-valued self-orthogonal finite-length sequence has an impulsive autocorrelation function with zero sidelobes except both shift ends. This paper presents a convolutional coding data transmission system using the sequence. A synchronizing sequence and a data train are convolved with another sequence, to be changed to a Gaussian signal. The signal is quantized and transmitted through a channel, and a received signal is correlated with the respective sequences. This system suppresses the channel noise and the distortion on the amplitude limitation and the quantization and brings an impulsive synchronizing pulse to measure multipath.
