Slope Intercept Model Estimation for MIMO–OFDM System in the WiMAX Environment
Authors: ,
Abstract: Channel fading in complex as well as in erratic manner, a rare spectrum of radio type, restrictions on the energy and the dimensions of mobile nodes are the prime restraints in communications of wireless type. Centred on these limitations novel schemes are put forth. Worldwide Interoperability for Microwave Access (WiMAX) is a promising domain to pursue work for wireless communication of broadband type, amidst a variety of emerging schemes. The scheme of WiMAX is a consistent method among IEEE 802.16d and among the principal of the WiMAX schemes, one can name Orthogonal Frequency Division Multiplexing (OFDM) as the core. A model of practical channel is needed to analyse the WiMAX method’s performances. Inclusive of Stanford University Interim (SUI) channel also known as slope intercept model, several models of channel are suggested to replicate the global situation. Lime light shone on this scheme prompting many a researchers to pursue in the recent past. Employing a variety of SUI models of channel, this paper analyses the performances in the context of Normalized Means Square Error (NMSE) of IEEE 802.16d. By analysing performance of different algorithms, proficient channel estimation scheme is arrived.
