Abstract
Orthogonal time frequency space (OTFS) transmits information symbols in the delay-Doppler domain rather than in the time-frequency domain (as with OFDM). In its original version, OTFS uses transmit and receive shaping waveforms which are biorthogonal with respect to translations by integer multiples of basic time and frequency intervals. In this paper we examine the performance of OTFS using general waveforms. Based on a discrete model of the modulation/demodulation procedure, we compute error probability, and we discuss the amount of diversity that can be achieved on fading channels.
