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…
Maximum Likelihood Time Synchronization for Zero-padded OFDM
Koosha Pourtahmasi Roshandeh, Mostafa Mohammadkarimi, Masoud Ardakani
Existing Orthogonal Frequency-Division Multiplexing (OFDM) variants based on cyclic prefix (CP) allow for efficient time synchronization, but suffer from lower power efficiency com…
Storage Allocation for Multi-Class Distributed Data Storage Systems
Koosha Pourtahmasi Roshandeh, Moslem Noori, Masoud Ardakani +1
Distributed storage systems (DSSs) provide a scalable solution for reliably storing massive amounts of data coming from various sources. Heterogeneity of these data sources often m…
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…
