Abstract :
In this paper a novel efficient spectrum shaping filter for fading nonisotropic channel model is being proposed. Wireless communication system´s evaluation is hampered due to time consuming, complex and inaccurate testing phase. The evaluation can be made proficient and dependable by creating channel environment for testing phase based on filter approach. During transmission of information through free space signal has to overcome fading and scattering effects. Channel environs has to be created by considering statistical properties and power spectra to replicate the nature of fading and scattering. Envelope shaping and spectrum filter can be realized for estimating channel effects. Envelope shaping filter can be modelled as IIR filter and spectrum filter as a multirate filter. In this paper a spectrum filter based on HDL is being proposed and ASIC results for 130nm standard library is considered.
