abstract = "This paper presents a novel Ultra-Wideband Orthogonal Frequency Division Multiplexing with Index Modulation (UWB-OFDM-IM) system, which combines the spectral efficiency of OFDM-IM with the robustness of UWB in multipath environments. The proposed system divides subcarriers into groups, activating only a subset to transmit QPSK-modulated symbols while leveraging subcarrier indices to carry additional information bits. The simulation results of the proposed technique compared with conventional UWB-OFDM. The results are as follows: 8.5 dB SNR gain at a BER of 10-3, a 1.8 dB reduction in PAPR, and a 6.02 dB improvement in spectral containment at 5 GHz. These improvements make UWB-OFDM-IM suitable for energy-constrained IoT applications, offering reliable connectivity in dense and multi-path environments.",
