A New Formula for the BER of Binary Modulations with Dual-Branch Selection over Generalized-K Composite Fading Channels
Imran Shafique Ansari, Saad Al-Ahmadi, Ferkan Yilmaz +2
Error performance is one of the main performance measures and derivation of its closed-form expression has proved to be quite involved for certain systems. In this letter, a unifie…
Cycle structure of permutation functions over finite fields and their applications
Amin Sakzad, Mohammad-Reza Sadeghi, Daniel Panario
In this work we establish some new interleavers based on permutation functions. The inverses of these interleavers are known over a finite field . For the first time…
Lowering the Error Floor of LDPC Codes Using Cyclic Liftings
Reza Asvadi, Amir H. Banihashemi, Mahmoud Ahmadian-Attari
Cyclic liftings are proposed to lower the error floor of low-density parity-check (LDPC) codes. The liftings are designed to eliminate dominant trapping sets of the base code by re…
An Efficient Approach Toward the Asymptotic Analysis of Node-Based Recovery Algorithms in Compressed Sensing
Yaser Eftekhari, Amir H. Banihashemi, Ioannis Lambadaris
In this paper, we propose a general framework for the asymptotic analysis of node-based verification-based algorithms. In our analysis we tend the signal length to infinity. We…
Network Capacity Region of Multi-Queue Multi-Server Queueing System with Time Varying Connectivities
Hassan Halabian, Ioannis Lambadaris, Chung-Horng Lung
Network capacity region of multi-queue multi-server queueing system with random ON-OFF connectivities and stationary arrival processes is derived in this paper. Specifically, the n…
