Wireless Communication today is heading towards dynamic spectrum allocation technology i.e. Cognitive Radio (CR). Increased demand over the usable spectrum has left no alternative than CR for seamless communication. Working in the dynamic spectrum allocation era demands flexibility and re-configurability from trans-receiver radio systems. The Software Defined Radio (SDR) thus forms the heart of CR. SDR incorporates adaptive algorithms for all processing blocks of Communication Systems. Noise over the channel in CR will also take dynamic nature. While transmission over such varying noise channels SDR must incorporate adaptive denoising algorithms. The paper focuses on such an adaptive optimisation approach for Image denoising.
