Abstract

OFDM technologies use copies of time domain signals. These include but not only: - Cyclic prefix of OFDM symbols, -SS & SSS signals in 4G LTE (& potentially 5G), - 5G Channel Estimation pilots symbols. When signals' copies are found, we can spare the associated DFE processing (for example CFR or DPD). We can even envision an automated scheme that detects if a chunk of data has already been processed and hence spare the associated processing.
