Implementation of Adaptive OFDM System Using FPGA
OFDM is a modulation as well as multiplexing technique which is now widely used in various high speed mobile and wireless communication systems because of its capacity of ensuring high level robustness against interference. In this paper the design and implementation of OFDM system will be illustrated as well as a detailed simulation of the OFDM system with 64-QAM to study the effect of various design parameters on the system performance. OFDM transceiver will be implemented using FPGA Spartan 3A kit. This adaptive system will be implemented using different digital modulation schemes as shown in the emulation results. All modules are designed using VHDL programming language.
Keywords: Orthogonal Frequency Division Multiplexing (OFDM); Field Programmable Gate Array (FPGA); Hardware Description Language (HDL); Inverse Fast Fourier Transform (IFFT); Fast Fourier Transform (FFT); Cyclic Prefix (CP); Bit Error Rate (BER); Signal to Noise Ratio (SNR).
