Mapped ADMM: A Robust Algorithm for 1-Bit mMIMO Detection
Mohammad Amin Keshmiri, Masoud Ardakani
Recently, it has been reported that one-bit massive MIMO (mMIMO) detection is equivalent to a binary classification problem that can be solved efficiently using support vector mach…
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…
Efficient Massive Machine Type Communication (mMTC) via AMP
Mostafa Mohammadkarimi, Masoud Ardakani
We propose efficient and low-complexity multiuser detection (MUD) algorithms for Gaussian multiple access channel (G-MAC) for short-packet transmission in massive machine type comm…
Fast Encoding and Decoding of Flexible-Rate and Flexible-Length Polar Codes
Muhammad Hanif, Masoud Ardakani
This work is on fast encoding and decoding of polar codes. We propose and detail 8-bit and 16-bit parallel decoders that can be used to reduce the decoding latency of the successiv…
On minimum distance of locally repairable codes
Mehrtash Mehrabi, Massoud Ardakani
Distributed and cloud storage systems are used to reliably store large-scale data. Erasure codes have been recently proposed and used in real-world distributed and cloud storage sy…
