Title: Innovations of Mohammad Pakravan in Communication Systems
Introduction
Mohammad Pakravan is an accomplished inventor based in Ottawa, Canada. He has made significant contributions to the field of communications systems, particularly through his innovative patent that addresses challenges in multicarrier modulation.
Latest Patents
Pakravan holds a patent titled "Frame alignment and time domain equalization for communications systems using multicarrier modulation." This invention involves a discrete multitone (DMT) receiver equipped with a time domain equalizer (TDEQ). The TDEQ is trained during initialization using an estimated channel impulse response (CIR). To prevent wrap-around of the estimated CIR concerning the DMT frame alignment and to eliminate leading zeroes, the estimated CIR is circularly advanced relative to the frame alignment for training the TDEQ. During subsequent communications of DMT symbols via the channel and the TDEQ, the equalized samples of the received DMT symbols are buffered to compensate for the advance of the estimated CIR in the initialization process and for a delay in the TDEQ.
Career Highlights
Pakravan is associated with Nortel Networks Corporation, a prominent player in the telecommunications industry. His work at Nortel has allowed him to focus on advancing communication technologies and improving system efficiencies.
