Cloud Transmission frequency domain cancellation

Cloud Transmission (Cloud Txn) is a spectrum efficient broadcasting system, which removes the co-channel interference through the use of robust forward error correction (FEC) codes. Nevertheless, the main drawback of this approach is that the system overall data rate is reduced. As a solution, the system proposes a spectrum overlay technology to increase data throughput while maintaining the robustness. The goal of this paper is to further explain and justify the spectrum overlay and corresponding frequency domain cancellation techniques.
