Performance on ICI Self-Cancellation in FFT-OFDM and DCT-OFDM System

Journal of Function Spaces, 2015
In orthogonal frequency division multiplexing (OFDM) system, the existence of frequency offset in AWGN channel affects the orthogonality among the subcarriers and consequently introduces the intercarrier interference (ICI). The paper investigates new ICI

A Novel Approach for Cancelation of Nonaligned Inter Spreading Factor Interference in LoRa Systems

IEEE Open Journal of the Communications Society, 2022
Long Range (LoRa) has become a key enabler technology for low power wide area networks. However, due to its ALOHA-based medium access scheme, LoRa has to cope with collisions that limit the capacity and network scalability.

Improved Iterative Parallel Interference Cancellation Receiver for Future Wireless DS-CDMA Systems

EURASIP Journal on Advances in Signal Processing, 2005
We present a new turbo multiuser detector for turbo-coded direct sequence code division multiple access (DS-CDMA) systems. The proposed detector is based on the utilization of a parallel interference cancellation (PIC) and a bank of turbo decoders.
