Smart radio interference mitigation techniques for mutual coexistence

This Thesis focuses on an interference mitigation technique called Detect And Avoid (DAA), a terminology that was made popular by Ultrawideband technology. This report specifically addresses design and implementation challenges associated with DAA in the context of coexistence between UWB and WiMAX technologies. However the design problems, implementation issues and candidate solutions discussed herein are generic enough to be applicable to other radio architectures that use similar core building blocks, particularly for digital radio implementations that contain Fast Fourier Transform (FFT) engines. Another important aspect highlighted in this report is the impact of non-technical considerations such as regulatory requirements and cost implications on choice of certain approaches over others. Such considerations can be decisive from a hardware design perspective especially in low-cost, low-power consumer electronics market.
