Study of Characteristics of Digital Radio Networks Taking into Account Capture Phenomenon

Characteristics of radio networks with multiple access and interface ALOHA are studied, given the availability of capture. Analytical expressions for dependence of density of the average transfer speed on distance to the reception point are derived for networks with the constant traffic density. The traffic density has been estimated for networks with the constant average speed density. The capture phenomenon in radio channels with the double phase modulation, frequency modulation with continuous subcarrier phase and the carrier frequency or amplitude modulation is simulated. The total average speed for the radio networks with the above modulation types is estimated on the basis of simulation results.
