Performance Analysis of Binary FSK Signals with L-Fold Diversity Selection Combining Techniques in a Nakagami-M Fading Channel

摘要

This thesis investigates the performance analysis of a non-coherent Binary Frequency Shift Keying (BFSK) receiver using Selection Combining techniques over a frequency non-selective, slowly fading Nakagami channel. These techniques are independent of the number of diversity branches, so simpler receivers can be employed. First order selection Combining (SC), second order Selection Combining (SC-2) and third order Selection Combining (SC-3) techniques are evaluated and compared to each other. Numerical results show that the performance improves as the order of Selection Combining techniques increases.
