Improving OFDM: Multistream faster than Nyquist signaling
Author
Summary, in English
Mazo's concept of Faster Than Nyquist signaling is extended to pulse trains that modulate adjacent subcarriers, in a manner similar to orthogonal frequency division multiplex (OFDM) transmission. Despite pulses
that are faster than the Nyquist limit and subcarriers that significantly overlap, the transmission system achieves the isolated pulse error performance. Systems with at least twice the spectral efficiency of OFDM can be achieved at the same error probability. Receiver
design is challenging, and we report tests of several options.
