Özet
The emergence of the Internet of Things (IoT) has driven the demand for connectivity solutions that operate efficiently while remaining fully compatible with legacy orthogonal frequency division multiplexing, (OFDM). This letter presents a novel transceiver architecture for IoT connectivity, designed within the framework of CP-OFDM systems. The proposed scheme embeds frequency-shifted Zadoff-Chu (ZC) sequences into a selected set of OFDM subcarriers. These subcarriers are integrated alongside conventional data symbols, ensuring full spectral compatibility and coexistence with legacy cellular systems. At the receiver, a correlation-based detection approach is employed for symbol recovery, eliminating the need for FFT-based demodulation. The proposed design is described, and its detection performance is evaluated against LoRa under various scenarios, demonstrating its effectiveness for resource-constrained IoT deployments.
