Wimax which represents world wide interoperability for microwave access is a major part of broad band wireless network having IEEE802.16 standard providing fixed and mobile platform for broadband internet access. The Wimax forum has adopted IEEE 802.16 OFDM PHY layer for the equipment manufacturer due to its robust performance in multipath environment. In this paper we investigate the simulation performance of IEEE 802.16 OFDM PHY layer. The Stanford University Interim (SUI) channel models are selected for the wireless channel in the simulation and we also investigate the estimation of channel at high frequencies with conventional Least Square (LS) and Minimum Mean Square (MMSE) estimation algorithms. Channel state information for OFDM systems based on pilot carrier is carried out through Matlab simulation. The performance of MIMO OFDM is evaluated on the basis of Bit Error Rate (BER) and Mean Square Error (MSE) level.

A new approach is used to design the printed Band pass Filtering Antenna. Multifunction, multi-use components with design of miniaturization are in considerable demand in wireless communication systems. In these systems, both antennas and filters are usually larger components compared to other components. A single compact module can be designed to provide both the desired filtering and radiating performances. The microstrip parallel line coupled band pass filter with fractal antenna integration approach reduces the integrated antenna system size and the transmission loss between the filter and the antenna and is used in WLAN, Bluetooth and WIMAX. The fractal antennas with integrated parallel line coupled band pass filter are printed on the same layer. The impedance between the antenna and the filter is optimized to improve the performance of the system without restricting it to 50Ω.

Considering the changing patterns in correspondence framework, the necessity of an ease, insignificant weight and a position of safety receiving wire is genuinely necessary. In this way, satisfying the previously mentioned necessities microstrip fix receiving wires are planned. The goal of this paper is to plan a 2X1, 1X2, and 4X1 fix receiving wire cluster and furthermore investigate their points of interest and burdens contingent on the outcomes acquired. Reception apparatus parameters for example, radiation design, receiving wire gain, directivity and control acquired are contemplated. The work includes structuring of 2X1, 1X2 and 4x1 fix cluster at resounding recurrence. The results are gotten utilizing Advance Design System (ADS).Keywords
