An OFDM system is combined with multiple-input multiple-output (MIMO) in order to increase the diversity gain and system capacity over the time variant frequency-selective channels. However, a major drawback of MIMO-OFDM system is that the transmitted signals on different antennas might exhibit high peak-to-average power ratio (PAPR).In this paper, we(More)
This paper addresses the problem of binary phoneme classification via a neural net segment-based approach. Phoneme groups are categorized based on articulatory information. For an efficient segmental acoustic properties capture, the phoneme associated with a speech segment is represented using MFCC's features extracted from different portions of that(More)
