The receiver will be consisted of direct detection receiver with equal gain combining technique. The analysis will be carried out for the MIMO FSO system to find the expression for the output signal & photo detector currents in presence of strong atmospheric turbulence. The signal to noise ratio (SNR) and the unconditional BER will be evaluated numerically for different system parameters. The degradation in system performance due to the channel effect and improvement in receiver sensitivity will be determined numerically. Optimum system parameters will be determined for a given system BER.51 pagesenBRAC University thesis are protected by copyright.
