Multicarrier CDMA for Data Transmission over HF Channels: Application to "Digital Divide" Reduction

Abstract

High-Frequency (HF) ionospheric transmission has been employed for many years for long-distance radio bridging both in military and civil applications. In these last decade, the employment of the most advanced transmission techniques to HF channels raised a considerable interest in R&D. Orthogonal Frequency Division Multiplexing (OFDM), Direct Sequence… (More)
