Abstract

Low Rate Orthogonal Convolutional Codes (LROCC) have been confirmed an outstanding performance in AWGN channel with multiple users, such as the en-route situation in the aeronautical communications with several aircrafts. However, the orthogonal sequences in LROCC still suffer from multipath interference in fading channel, which degrades the performance in practical scenarios. In this paper, extended CCK sequences have been applied instead of orthogonal sequences to form the low rate convolutional codes, which enable the aeronautical communications system a strong capability in the multipath interference cancellation(e.g., low elevation flight).
