Sažetak
In this paper, we propose a low complexity multiuser communication system based on frequency index modulation that suits internet of things (IoT) applications. This system aims to reduce the transmitted energy and the peakto- average-power ratio (PAPR) of orthogonal frequency-division multiplexing (OFDM) systems and to perform without sacrificing data rate in comparison to conventional OFDM. In this design, OFDM-like signals are used to make the implementation of the system easy by virtue of fast Fourier transform (FFT). In the proposed scheme, the OFDM bandwidth of NFIM total sub carriers is divided into NB equal number of sub- bands, with N subcarriers in every sub-band. At the transmitter side of each sensor, the bit stream is divided into two blocks: mapped and modulated. The bits within the mapped block are used to activate the corresponding subcarrier in its predefined sub-band in order to carry the data of the modulated block, while the other N 􀀀 1 subcarriers are nulled out. At the receiver, the FFT is performed first, then the square-law envelope detector is applied to estimate the active frequency index to recover the mapped bits, followed by a conventional demodulation to demodulate the transmitted bits. Once the system is presented and analysed, energy efficiency, PAPR and complexity are studied to show the features of the proposed scheme. Moreover, we derive closed-form expressions of the bit error rate (BER) performance over Rayleigh fading channels and we validate the outcome by simulation results.With the characteristics exhibited in this work, the proposed system would constitute an excellent candidate for wireless sensor applications, where it represents a simpler substitution for frequency- hopping (FH) based architectures, in which the hops carry extra bits.
