On QoS aspects with different coding and channel conditions for a WiMAX based network

Abstract

The WiMAX forum has adopted IEEE 802.16 Orthogonal Frequency Division Multiplexing (OFDM) based adaptive Physical Layer (PHY) layer due to its robust performance and provision of various mechanisms to improve Quality of Service (QoS). This paper evaluates the performance of PHY layer with various QoS aspects for different coding schemes and channel conditions. A robust PHY layer with improved QoS performance is developed from the investigations.
