Iterative Receiver Design for FTN Signaling Aided Sparse Code Multiple Access

Iterative detectors for trellis-code multiple-access

Trellis-code multiple-access (TCMA) is a narrowband multiple-access scheme based on trellis-coded modulation. There is no bandwidth expansion, so users occupy the same bandwidth as one single user. The load of the system, in number of bits per channel use, is therefore much higher than the load in, for example, conventional code-division multiple-access systems. Interleavers are introduced as a...

Iterative Receiver Design With Off-the-Grid Sparse Channel Estimation

Recent progress in wireless receiver design has been towards iterative processing, where channel estimation and decoding is considered a joint optimization problem. Sparse channel estimation is another recent advancement, which exploits the inherent structure of those wireless channels that are composed of a small number of multipath components. In this work we design iterative receivers which ...

Analysis of Code Aided MMSE Receiver for Transceiver Impairments and Multiple Access Interference in CDMA Systems over Rayleigh Fading Channels

This paper deals with the method to study and improve the interference due to transceiver impairments which occurs due to the some impairments at transmitter and receiver end and other interference such as Multiple access interference sharing of resources like narrow bandwidth and spectral bandwidth in Rayleigh fading channels. Fading is major source of impairment in wireless communications bec...
