Abstract :
In this paper we present a simple convolution encoder that is implemented over mixed signals of various types of real number values. We make use of the Orthogonal Frequency Division Multiplexing (OFDM) technique for the band pass modulation methods. Here we also make use of the multiband OFDM transmitter that consists of blocks performing IFFT, interleaving, puncturing of sequences and modulation using orthogonal sequences. The main purpose of our paper is to set a basic example of working with higher error correcting codes over real number sequences directly using Fourier transforms and implement it through the noisy AWGN channel using the latest OFDM technique.[1].
