Otfs precoding
Weba given multicarrier waveform with the addition of precoding and post-processing units to the modulator and demodulator. In this paper, we present discrete-time formulation of an OFDM-based OTFS system. We argue against deployment of window functions at the OTFS transmitter in realistic scenarios and thus limit any sort of windowing to the ... Webbases for precoding in the frequency domain are analyzed. The basic concept of OTFS is discussed in the white paper [2] and the patents published by Cohere [1]. First …

Webprecoding along the frequency dimension to the Fourier transform, specifically FFT as in the case of OTFS. Such precoding along the frequency dimension transforms the time-frequency information samples directly into the delay-time domain, thereby bypassing the need for an OFDM modulator. Using FFT as above, the 2-D precoding along the frequency- WebJul 14, 2024 · One of them is used for precoding and power allocation, which is a way to combat multi-path interference. The next module does spatial spreading to combat interference after spatial multiplexing. The actual variant of OTFS used in this work is spatially spread orthogonal time frequency space (SS-OTFS).
