This paper studies the performance of block coding on an additive white Gaussian noise channel under different power limitations at transmitter. New lower bounds are presented for minimum error probability codes satisfying maximal and average constraints. These tighter than previous results in finite blocklength regime, yield a better understanding structure good limitation. Evaluation these sh...

Objectives: In this work, we investigate suitable techniques to reduce the Peak Average Power Ratio (PAPR) for advanced modulation schemes in order obtain better performance than current or commonly used Fourth Generation (4G) and Fifth (5G). Methods: The proposed scheme incorporates a combination of Selective Mapping (SLM) Partial Transmission Scheme (PTS) thereby efficiently minimizes PAPR co...
