The sensitivity of bit error rate (BER) performance in multi-carrier (OFDM) and single-carrier
SPIE Proceedings, 2012Recently, the single-carrier and multi-carrier transmissions have grabbed the attention of industrial systems. Theoretically, OFDM as a Multicarrier has more advantages over the Single-Carrier especially for high data rate. In this paper we will show which one of the two techniques outperforms the other.

Telecommunication Systems currently in operation make use of multiple connection in order to enhance the service reliability and to reduce electromagnetic field levels. Connection is handled by coded signals, in often unstable multipath condition, and, in some case, by smart and/or multitasking antennas.

In wireless communication, turbo and modified turbo codes are used as forward error correction (FEC) codes to improve the performance of the system in terms of bit error rate (BER). This work revisits the FEC using conventional turbo codes and proposes few modifications in them to obtain modified turbo codes.

The work in the field of wireless communication these days is directed towards the efficient usage of the available spectrum as the spectrum scarcity keeps haunting people in general and communication engineers in particular. This puts an upper limit on the development of new spectrum hungry applications.

Optical CDMA is one of the few multiple access concepts which permit concurrent, non-blocking virtual channels. However, conventional approaches with linear codes induce stringent device requirements which stem from the bandwidth inefficiency, also denoted as the time penalty, of CDMA.

An analytical approach is presented to evaluate the Bit Error Rate (BER) performance of a multicore fiber (MCF) communication system with On-Off Keying (OOK) modulation scheme. The expressions of the signal power at the output of the different cores of the MCF with excitation to any one of the cores is found out along with the crosstalk due to coupling

New closed form expressions for the average error rate of MC-CDMA systems in Nakagami-m fading channels are derived based on the exponential approximation of the Q-function. Numerical results by substituting in these expressions are presented and compared to results provided by other researchers using computer simulations or numerical integrations ...
