ABSTRACT

Future sixth-generation (6G) and new wireless communication systems are expected to enable massive volumes of data transfer with utmost high reliability, low latency, and less reception complexity to meet the needs of IoT-based wearable devices. To fulfill these requirements, we propose a novel signal superposition-based dual transmission communication technique that is capable of simultaneously improving data rates from one side and reducing data errors from another side. The proposed system uses superimposed auxiliary signals (based on wireless channel characteristics) to eliminate interference and the channel effects at the reception side. The superimposed auxiliary signals provide low complexity and minimum processing at the receiver side, which results in reducing the power consumption and delay in future communication systems and devices. The obtained simulation results unveil that the proposed technique provides better throughput, improved reliability, less complexity, making it suitable for low power consumption, limited processing applications such as IoT devices.
