“…Enhances the BER performance of a network when compared with conventional MC-CDMA technique [40] subcarrier allocation has been presented as an optimization problem in [41], which aims to maximize the throughput capacity of the system. Non-contiguous partitioning based algorithm performs better than contiguous partitioning as it preserves the frequency diversity gain.…”

ABSTRACT:Over the last decade, a large number of pioneering works have provided foundations for both theory and applications of Wireless Ad hoc Networks (WLAN). As ad hoc technology is becoming the demand of present and future trends that needs for a reliable communication link having minimum BER and power. This review work presents the impact of mobility, and energy efficiency and clustering on optimization of Bit Error Rate (BER) and power as well as on throughput. An analysis review is made on Network coding scheme to optimize BER and throughput. And finally how these factors vary in WLAN is discussed in conclusion.

“…In this section, group assignment strategies considered within this study are discussed. A brief review of simple schemes consistent with approaches adopted in single-cell analysis is presented, that is, random group assignment (RGA) [17] and best subcarrier group assignment (BSGA) [2,[5][6][7]]. This will be followed by introducing the proposed interference-based strategies, that is, LIGA and BCRGA.…”

“…follows a normal distribution (since large-scale path-loss is usually log-normal distributed) and σ (b, j) kb is related by (6) to σ (b, j) kb that follows a gamma distribution (since σ (b, j) kb is expressed as the sum of G exponential random variables for Rayleigh fading channels). On the other hand, computation of the probability density function f I (b, j) k (i) is not necessarily straightforward since I (b, j) k heavily relies on RRM operation across the entire network.…”

Two interference-based subcarrier group assignment strategies in dynamic resource allocation are proposed for MC-CDMA wireless systems to achieve high throughput in a multicell environment. Least interfered group assignment (LIGA) selects for each session the subcarrier group on which the user receives the minimum interference, while best channel ratio group assignment (BCRGA) chooses the subcarrier group with the largest channel response-to-interference ratio. Both analytical framework and simulation model are developed for evaluation of throughput distribution of the proposed schemes. An iterative approach is devised to handle the complex interdependency between multicell interference profiles in the throughput analysis. Illustrative results show significant throughput improvement offered by the interference-based assignment schemes for MC-CDMA multicell wireless systems. In particular, under low loading conditions, LIGA renders the best performance. However, as the load increases BCRGA tends to offer superior performance.
