Abstract :
Performance analysis of a bandlimited nonorthogonal waveform transmission (NOWT) scheme for high data rate wireless communications is presented. The technique is a potential alternative to classic orthogonal multiplexing techniques such as OFDM and QAM. It shows faster data transmission rate than Nyquist rate, and considerable performance gain compared with orthogonal techniques, as well as much lower peak to average power ratio (PAPR). The error probability in AWGN channel is derived, and the free squared Euclidean distance of NOWT signal is no more than the minimum squared distance of its modulation constellation. Analysis and numerical results demonstrate that the bandwidth efficiency and capacity of cod-ed/uncoded NOWT technique is higher than Nyquist signalling and orthogonal techniques.
