Improved and High Frequency FPGA Realization of Address Generator for WiMAX Deinterleaver

A novel FPGA architecture of Wimax Deinterleaver circuit is presented, which uses a simplified circuit to reduce the overall design complexity, The floor function used to show the variations in incoming bits in IEEE 802.16E format are implemented by simply discarding some portion of the binary number, which simplifies the algorithm., allowing for an efficient and low-complexity FPGA implementation, supported by its mathematical foundation. When compared to conventional LUT-based approaches, this approach is both innovative and highly effective. utilizing the FPGA's inbuilt multiplier, it optimises resource allocation for a range of modulation schemes, such as 64-QAM with all possible code rates, 16-quadrature amplitude modulation (16-QAM), and quadrature phase-shift keying (QPSK). The utilisation of FPGA resources is significantly enhanced by the suggested approach.
