摘要: | This work presents a new technique which can blindly perform the fine synchronization for single-carrier block-transmission (SCBT) systems without using unique words (UW). The proposed technique, called simplified weighted LS method for single-carrier systems (SWLS-SC), combines the concept of the decision feedback structure and SWLS estimator for OFDM systems. Together with specifically derived weighting factors, the proposed scheme has much better estimation accuracy than the well-known linear least-square (LLS) method for SC systems, while its BER performance can approach that of the ideal synchronization condition. With the proposed estimator, the system throughput can be further increased, because there is no need to insert UW for fine synchronization. The theoretical estimation bounds are also derived to prove the effectiveness of the proposed scheme. |
