Abstract:

The paper is essentially a discussion paper which introduces, with the aid of data from real radio paths of different types, the concept of multiple Propagation mechanism radio communication in the HF and low-VHF bands up to about 100 MHz. The radio system architecture necessary to exploit such a multiple-mechanism environment is then considered, with particular reference to the channel encoding and channel evaluation procedures required. Digital signal processing is assumed.
