WebThe recently proposed Orthogonal Time Frequency Space (OTFS) modulation has been shown to be robust to mobility induced Doppler spread in next generation communication systems. Due to dense network deployment, next generation communication systems are expected to experience significant co-channel interference. Therefore, there is a need to … Webchannels. OTFS deploys the Doppler-delay plane to multiplex the transmit data where the time variations of the TV channel are integrated over time and hence the equivalent channel relating the input and output of the system boils down to a time-invariant one. This signaling technique can be implemented on the top of WebThe OTFS waveform is based on the idea that the mobile wireless channels can be effectively modelled in the delay-Doppler domain. This domain provides a sparse representation closely resembling the physical geometry of the wireless channel. flathead county jury duty
