Abstract�� A statistical channel model for the pilotless helicopter multiple-antennae communication was derived based on the single-antenna aeronautical channel model. Characteristics of delay spread, Doppler spread and angular spread were discussed. Mask effect of fuselage and interference of the multiple-antennae were researched. An effective and accurate simulation model was derived from the proposed model. Simulation methods for delay power spectrum, spatial correlation, Doppler spectrum and mask effect of fuselage were presented respectively. Numerical simulations of single-antenna and multiple-antenna channel were carried out under three flying conditions: reroute, circled, taking off and landing. Good performance of differential space-time code was confirmed through simulation. The model is useful for the modulation/coding design of pilotless helicopter multiple-antennae communication system.
Keywords�� unmanned aerial vehicles   multi-input multi-output systems   model building   space-time block coding
