A New Dual Transmission Technique Employing Auxiliary Signal Superposition for Improving the Data Rate and Diversity in Next-Generation Communication Systems

Next-generation wireless communication systems desire higher data rates, upgraded system reliability, and better deployment of power resources than currently employed systems. To address this challenge, in this work, we propose a new, novel dual transmission technique that provides better spectral efficiency and much-enhanced reliability at the receiver. In the proposed technique, new intelligent auxiliary signals are designed based on the wireless channel characteristics so that interference can totally be eliminated, and channel effects can be mitigated at the receiver while ensuring less complexity reception. The benefits and novelty of the proposed system are presented using extensive mathematical analysis and testified by numerical simulation. The outcome obtained reveals that the proposed model achieves better throughput, enhanced reliability, and less complexity, thus making it suitable for low power consumption and limited processing applications such as IoT scenarios.
