In this paper, we propose a Swarm Intelligence based Resource Allocation Algorithm (SIRAA) for optimum allocation of available spectrum holes to cognitive radio users. Usage statistics reveal that large portion of the spectrum are under utilized due to stringent licensing policy. Spectrum utilization ranges from only 15% to 85% with a high variance in both(More)
This paper presents field programmable gate array (FPGA) implementation of the forward/inverse discrete wavelet transform for denoising Fiber Optic Gyroscope (FOG) signal. In this work an extensive study on the effect of different threshold techniques of DWT algorithm are carried out denoising the FOG signal. Different architectures such as multiply and(More)
