Long Term Evolution (LTE): Next Generation Wireless Communication of NASA for Satellite Engineering

Md Mahmudul Hasan,

This research work is anticipated for verifying the implementation of Long Term Evolution (LTE) over satellite in forward link for the next generation communication of NASA for satellite engineering or extraterrestrial purposes. Recent developments in wireless communication such as MIMO technique that allow improving the received signal quality and capacity, in combination with OFDM makes the signals more robust against delay spread in frequency selective channel. A dual satellite Orthogonal Frequency Division Multiplexing and Multiple-Input and Multiple-Output (OFDM-MIMO) model is considered which provides a handy and robust resource over satellite channel for this purpose. It is OFDM in aggregation to Quadrature Phase Shift Keying (QPSK) with Turbo Coding using 2×2 MIMO as specified for LTE 5 MHz BW, transmitted with satellite power delay profile has analyzed in terms of Bit Error Rate (BER). Spatial multiplexing and diversity are the two features that MIMO provides which has also been investigated. The investigation has been conducted considering downlink transmission over satellite forward link over dual-satellite 2×2 MIMO channel.
