A comparison between stationary and mobile digital VHF radio channels and channel models

This paper presents results of a study undertaken to determine Fritchman (1967) channel models for mobile as well as stationary (linking two points geographically fixed with respect to each other) VHF radio channels. These models were investigated with respect to four modulation schemes FSK, DPSK, Q...

description This paper presents results of a study undertaken to determine Fritchman (1967) channel models for mobile as well as stationary (linking two points geographically fixed with respect to each other) VHF radio channels. These models were investigated with respect to four modulation schemes FSK, DPSK, QPSK and 8-ary PSK. Predictions of P(m,n), the probability that a block of n digits will contain exactly m errors, are presented for each of the channels and modulation schemes investigated. Values of the amount of memory in each of these channels, as well as capacities are also presented. Some conclusions are drawn from these results.< >
