Convolutional 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 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 to an integer train and transmitted through a channel, and a received signal is correlated with the respective sequences. This system suppresses a channel noise and the distortion on the amplitude limitation and the quantization and brings an impulsive synchronizing pulse to measure multipath.
