Low Complexity Time Synchronization for Zero-padding based Waveforms

Koosha Pourtahmasi Roshandeh, Mostafa Mohammadkarimi, Masoud Ardakani

The discussion on using zero padding (ZP) instead of a cyclic prefix (CP) for enhancing channel estimation and equalization performance is a recurring topic in waveform design for…

A general framework for weighted sum-rate and common-rate optimization

Koosha Pourtahmasi Roshandeh, Masoud Ardakani, Chintha Tellambura

In this paper, we propose a framework for solving a class of optimization problems encountered in a range of power allocation problems in wireless relay networks. In particular, po…
