Space Power Block Coding (SPBC): A Novel 6G Method for Providing High Throughput and Ultra-Reliability for Processing-limited Receivers

Abstract

In this work, we introduce a new transmission method inspired by space-time block-coding (STBC) with or-thogonal frequency division multiplexing (OFDM) to jointly improve spectral efficiency and reliability, while reducing receiver complexity, which is deemed as a critical requirement for processing-limited IoT devices. The newly developed transmission method, coined as space-power block-coding (SPBC), utilizes the superposition of specially precoded data streams to be trans-mitted to serve a single end-receiving device with two antennas, while keeping the receiver structure unchanged, thus making it compatible with any current or future modern smart end-devices. The proposed scheme objectives are to improve spectral efficiency, increase the link throughput, and enhance reliability for a single OFDM-based receiver. In particular, the user data streams are superimposed with intelligently designed pre-coders intending to cancel the intentionally introduced interference at the transmitter as well as the channel impact and effect at the receiver, while ensuring that the reception process is much simpler and way less complex. Moreover, we analyze the obtained comparative simulation results, where it is found that the performance of the proposed design is significantly higher than that of its conventional counterparts.
