Iterative receiver for flip orthogonal frequency division multiplexing and proposed 5G modulation techniques

<p> In Optical Wireless Communication (OWC) systems, the technique of Flip-Orthogonal Frequency Division Multiplexing (Flip-OFDM) is applied, where the positive segment and negative segment of the signal are transmitted on two continuous OFDM sub-frames. Conventionally in Flip-OFDM, data is recovered by simply subtracting the negative sub-frame from the positive sub-frame. But the signal survey confirms that the information in both sub-frames gets disrupted during signal propagation and an incorrect detection of the received values takes place at the detector. </p><p> An iterative receiver is proposed that utilizes the input signal values along with the received signals sub-frames to improve the efficacy of the Flip-OFDM. The Matlab software is used to design the transmitter and iterative receiver. Features such as cyclic prefixing, frame multiplexing, and channel characterization are included in the design. </p><p> The results of the simulation depict that the suggested receiver delivers a superior Bit Error Rate (BER) and Signal to Noise Ratio (SNR) gain when compared to the conservative receiver.</p>
