Designing very high speed wireless links that offer good quality-of-service and range capabilities in non-line-of-sight (NLOS) environment constitutes a significant research and engineering challenge. WiMAX is a NLOS wireless broadband technology based on the IEEE 802.16 and ETSI HiperMAN standards utilizes orthogonal Frequency Division Multiplexing (OFDM) based technology with an all-IP core network that delivers superior performance with high throughput, low latency, advanced security and QoS functionality. In order to increase the range and reliability of WiMAX systems, the IEEE 802.16 standard supports optional multiple-antenna techniques such as Alamouti Space-Time Coding (STC) and Multiple-Input Multiple-Output (MIMO) systems. In this paper, the BER performance of high rate LDPC-Coded SISO/ MIMO fixed WiMAX systems are evaluated using OFDM and equalisation schemes. The high rate code generation is possible using BIBD design analysis and in this way new LDPC codes have been generated and tested over fixed Wireless WiMAX SISO/MIMO systems.
