Abstract: Worldwide interoperability for microwave access (WiMAX) has been found to be an emerging technology with significant potential that is poised to revolutionize the broadband wireless internet access market. To keep up with noteworthy growth in the demand of wireless broadband systems, new technologies and architectures are needed, which can improve the system performance and network scalability while significantly reducing the cost of equipment. Thus with increasing cost pressures on many wireless equipment makers, there is a significant drive to reduce both capital expenditure and operating expenditure cost attributes of the communication systems infrastructure. The significant requirements for these systems include low cost in terms of lesser silicon area, power consumption, processing speed, flexibility etc. Digital Up Converters (DUC) and Digital Down Converters (DDC) are very important and integral part of a WiMAX system. As they utilize the major resources, therefore their low cost design and efficient implementation can result in low cost WiMAX system with improved performance. In this thesis, design and implementation of a low cost interpolation and decimation stages of WiMAX DUC and DDC with improved performance are proposed. newlineIn this thesis different FIR filter design techniques like Window based FIR filter design, frequency sampling based FIR filter design, maximally flat FIR filters design, equiripple FIR filter design, minimum mean square error FIR filter design, minimum phase FIR filter design and Nyquist FIR filter design are discussed and compared to explore the suitable design for designing low cost interpolation anddecimation filters. Due to their low implementation complexity, Nyquist FIR filter designs are used in the proposed design of efficient interpolation and decimation filters for DUC and DDC. newlineDirect and polyphase structures can be used for the implementation of interpolation and decimation filters..
