As OFDM has become the basis of many of telecommunication standards due to its ease of implementation, stability and efficiency, Faster-than-Nyquist signaling became an interesting base for envisioned telecommunication breakthrough, since it is based on an already used and successfully implemented technology which is OFDM, and it inherently obtains the legacy system merits, at the expense of system...
Cooperation among self-organized femtocells (SOFs) becomes an optimization technique to induce a fair resource allocation. However, cooperation performance is restricted by backhaul limitations. In this paper, an energy efficient system design for cooperative SOFs is proposed. A new spectral resource management is used to avoid the uplink co-tier interference depending on less signaling overhead resulting...
In this paper, we consider a switch-and-examine combining (SEC) diversity scheme operating over independent and identically distributed (i.i.d) branches assuming an α-μ fading channel. We derive expressions for the average symbol error rate (ASER) for a class of coherent modulation techniques considering this fading model as well as expressions for the ergodic capacity under the same assumptions....
The paper proposes an approach to scale-down the LDPC code length, thus saving memory and processing power, without significantly sacrificing the code robustness. the paper describes how to use specific Low Density Parity Check (LDPC) codes for Digital Video Broadcasting Terrestrial Second Generation DVB-T2. While the original LDPC codes are rather long 16200 bits and 64800 bits, we propose to reduce...
Motivated by the generalization of the α-μ distribution in describing the small-scale fading over wireless channels, in this paper, closed-form expressions for the Shannon capacity of the α-μ fading channel operating under three adaptive transmission strategies are derived. These expressions are derived for the case of no diversity as well as for selection combining diversity with independent and...
In this paper, a multi-carrier code division multiple access (MC-CDMA) downlink mobile communication system employing pre-rake and dual transmit diversity is proposed. It combines high spectral efficiency with an immunity to channel dispersion and fading. It also ensures small size, cost and power consumption of the terminal. Theoretical and simulation results for the system under consideration are...
