"If you want an electrical engineer for your job, Mr. Ahmed should be the first choice on your list." Performed a great job of doing a circuitry layout from an existing PCB and then providing the Gerber files needed for us to get this PCB manufactured. Ahmed demonstrates exceptional skills in his field and possesses excellent communication abilities. His responsiveness and attentiveness to my feedback are remarkable.

Performance Analysis of OFDM with M-ary in Sum of Frequency-Selective Arbitrary Nakagami-m channels.

IEEE
Error rates of orthogonal frequency-division multiplexing (OFDM) signal using M-ary modulation in multipath slow fading Nakagami-m fading channel are considered. The exact probability density function of a sum of Nakagami-m random phase vector is used to derive a closed-form expression for the error rates of OFDM signals with arbitrary fading index m. This is done using the well-known moment generating function (MGF) analysis approach and in terms of the confluent hypergeometric function.

MRC Diversity Reception of OFDM with M-ary Modulation over Frequency-Selective Nakagami-m Fading.

Springer
In this paper, we take a close look at the performance of MRC diversity reception of OFDM signals in multipath slowly fading Nakagami-m channels. We derive an exact expression for the probability density function (PDF) of a sum of Nakagami-m random phase vectors, which is used to derive a closed-form expression for the error-rate of OFDM signals using multichannel reception with maximal ratio combining.
