Abstract
The need for optimised utilisation of scarcely available radio resources is prevalent. An efficient use of radio resources could lead to higher spectral efficient transmission on wireless channels. A promising scheme for wireless multimedia transmission at a lower cost is adaptive modulation and coding (AMC). In this paper, a new scheme for AMC is devised. A prioritized adaptive CDMA modulation and a graded resource technique is proposed for the maximisation of radio resources and for the realisation of next wireless generation. Rate compatible punctured turbo-code (RCPT) method and diversity technique with power controlled error (PCE) are also employed for better results. Simulations were carried out and the proposed algorithms demonstrate an improved throughput and robustness over the existing systems. These improvements arise from efficient radio resource management algorithms.
