Bandwidth management in the HAPS

Today the demand for sending data at high speed is increasing, so we propose variety of modulations to accelerate the speed. One technique is OFDM that contains sending data high byte rate frequency in gigahertz. However this data is presented in two forms: broadcast and multi-broadcast. These two forms help the applicants apply different ways such as satellites and communication towers. The need to use different services at high speed is increasing, this has made challenges for both planetary and aerial stations in which HAPS can be a good substitution. In this paper we analyze the wave band with OFDM modulation in the areas covered by HAPS to provide the applicants multi-media services with high speed.
