Title: Prakash Sethia - Innovator in OFDM Signal Processing
Introduction
Prakash Sethia is a notable inventor based in Bengaluru, India. He has made significant contributions to the field of signal processing, particularly in the area of orthogonal frequency division multiplexing (OFDM). His innovative work has led to the development of a patented system that enhances the evaluation of transmitters.
Latest Patents
Prakash Sethia holds a patent for "IQ impairment estimation in an OFDM signal." This patent describes a system and method for evaluating a transmitter by estimating IQ impairments in an OFDM signal generated by the transmitter. The OFDM signal may be received and represents a stream of symbols, each comprising a plurality of subcarriers. At least a subset of the subcarriers may be pilot subcarriers. The pilot subcarriers may be grouped into one or more groups based on specific conditions. An estimate of gain imbalance or quadrature skew of the OFDM signal may be calculated based on these groups, which can then be used to evaluate the transmitter.
