A PN (Pseudo Noise) based Channel Estimation (CE) algorithm using circular correlation is proposed, and is implemented in Single Carrier Frequency Domain Equalization (SC-FDE) system. The new CE algorithm is compared to typical frequency-domain algorithms, and it is found that new algorithm has lowest complexity and acceptable performance. A no-guard-interval PNA-SC-FDE (PN Assisted SC-FDE) system is studied and a simpler receiving procedure for interference-canceling based receiver is proposed. Simulation shows that the performance of receiver with interference-canceling and new CE algorithm can approach the performance of receiver with perfect CSI (Channel State Information).
