Range estimation of turbo coded waveforms over vegetative mountain blockage using link budget analysis

This paper is on the estimation of radio delivery range of multimedia data using turbo coded waveforms under terrain blockage. To achieve high throughput of multimedia data transmission with limited power under hostile radio propagation environment, multiple turbo coded waveforms of QPSK, 8-PSK, 16 and 64-QAM are employed. Towards effective estimation of the maximum transmission range, models of ground to ground (GTG) communication scenario under mountain blockage with/without vegetation is considered at 800 MHz. The estimated range is obtained by using extensive link budget analysis (LBA) based on the major parameters of transmit power, transmit/receive antenna heights and path losses under different channel conditions including AWGN and Rayleigh fading. Results of LBA show that terrain blockage of vegetative mountain is the worst radio propagation region. Doppler Effect also impacts on the reduction of estimated ranges as data rate increases.
