HAPS systems performance evaluation by simulation techniques at Ka band

The high altitude platforms stations (HAPS) represent an attractive option today for fixed broadband wireless access. This paper describes an analysis by simulation of the performance of a coded digital transmission system at Ka band for HATS in urban area when are considered weather impairments. Numerical results in terms of BER are obtained when (LDPC/M-APSK) coded signals are affected by fading caused by weather effects at Ka band. These effects are taken in consideration using a time series obtained by simulation. These results should be useful to a system designer of HATS communications systems at Ka band.
