- Full duplex is one of the main strategies for improving the spectral efficiency in DOCSIS 3.1 system. For self-interference cancellation of full duplex environment, various distortion elements should be estimated and compensated. Among the distortion elements of self-interference signal, channel distortion between transmission antenna and reception antenna is most dominant distortion element in the full duplex-based DOCSIS 3.1 system. This paper proposes an efficient frequency domain channel estimation and compensation technique of self-interference signal in DOCSIS 3.1 with full duplex. The proposed technique uses high-power data subcarriers as well as pilot symbols. The proposed technique can accomplish higher MER performance than existing channel estimation technique with only pilot symbols.
