Abstract

This paper presents an implementation of a low complexity Wavelet OFDM system based on Haar function. The OFDM transmitter generates the orthogonal signals, and the OFDM receiver detects the signals. The idea of low complexity is the arrangement and the multistage calculations of coefficients. It was shown that the number of multiplier and adder was reduced. Hardware model presented is scalable to higher speed, allowing possible implementation in electronic processors for advanced communication systems.
