Pilot based LS channel estimation for downlink HAPS channel
In real wireless communication system nowadays, accurate channel estimations are required since the performances at the receiver affect the whole system. This paper aims to evaluate the performance of pilot based channel estimation. In this study, we use Least Square (LS) technique to evaluate the performances of downlink Long Term Evolution (LTE) deployed via High Altitude Platforms (HAPS) LTE and Multiple Input Multiple Output (MIMO) antenna become one of important parts in high data rate wireless telecommunication lately. While HAPs is new non ground terrestrial technology that using air baloon as the platform that located in stratosphere make it an interesting technology to be investigating. By its position high above the earth's surface the link transmission need to be good and reliable. So that, in this study, Single Input Single Output (SISO) and MIMO Space Time Block Code (STBC) Alamouti is used as the MIMO antenna. As performance's indicator, BER (Bit Error Rate) to SNR (Signal to Noise Ratio) is used in this simulation.
