Superimposed Training-Based Joint CFO and Channel Estimation for CP-OFDM Modulated Two-Way Relay Networks
Joint copyright frequency offset (CFO) and channel estimation is considered for two-way relay networks (TWRNs).Existing estimators provide only the convolved channel parameters and the mixed CFO values.In contrast, estimators using a superimposed training strategy are developed for the individual frequency and channel parameters.Depending on the nu
