Optimality of Operator-Like Wavelets for Representing Sparse AR(1) Processes
Pedram Pad, Michael Unser
It is known that the Karhunen-Loève transform (KLT) of Gaussian first-order auto-regressive (AR(1)) processes results in sinusoidal basis functions. The same sinusoidal bases come…
New Power Estimation Methods for Highly Overloaded Synchronous CDMA Systems
Damoun Nashtaali, Omid Mashayekhi, Pedram Pad +2
In CDMA systems, the received user powers vary due to moving distance of users. Thus, the CDMA receivers consist of two stages. The first stage is the power estimator and the secon…
Capacity Achieving Linear Codes with Random Binary Sparse Generating Matrices
A. Makhdoumi Kakhaki, H. Karkeh Abadi, P. Pad +3
In this paper, we prove the existence of capacity achieving linear codes with random binary sparse generating matrices. The results on the existence of capacity achieving linear co…
Almost-Optimum Signature Matrices in Binary-Input Synchronous Overloaded CDMA
M. Heidari Khoozani, A. Rashidinejad, M. H. Lotfi Froushani +2
The everlasting bandwidth limitations in wireless communication networks has directed the researchers' thrust toward analyzing the prospect of overloaded Code Division Multiple Acc…
The Enigma of CDMA Revisited
K. Alishahi, S. Dashmiz, P. Pad +3
In this paper, we explore the mystery of synchronous CDMA as applied to wireless and optical communication systems under very general settings for the user symbols and the signatur…
Bounds for the Sum Capacity of Binary CDMA Systems in Presence of Near-Far Effect
P. Pad, M. H. Shafinia, S. M. Mansouri +2
In this paper we are going to estimate the sum capacity of a binary CDMA system in presence of the near-far effect. We model the near-far effect as a random variable that is multip…
