This work presents a blind fine synchronization scheme, which estimates and compensates residual carrierfrequency offset (RCFO) and symbol timing offset (STO) , for single-carrier frequency-domain equalization (SC-FDE) systems. Existing fine synchronization schemes for SC-FDE systems rely on time-domain unique words (UW) sequences as reference signals to(More)
A large-mode-area Erbium-doped fiber amplifier (LMA-EDFA) based all-fiber-integrated amplified compressor with ultrashort length of 5.37 m and ultralow pumping power (260 mW) is proposed. The LMAEDFA suppresses nonlinear soliton-self-frequency-shift effect happened during femtosecond pulse amplification, in which the fiber laser pulse is reshaped to a(More)
This work presents a new technique which can blindly perform the fine synchronization for single-carrier blocktransmission (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(More)
A dual-stage single-mode fiber (SMF) and large-effective-area fiber (LEAF) link for generating 48 fs pedestal-free pulses from a 40 MHz self-started additive pulse mode-locked erbium-doped fiber laser (APM-EDFL) with output peak power and pulse energy of 16 kW and 500 pJ, respectively, is demonstrated. With the SMF+LEAF link, a maximum pulse-width(More)
This work proposes two low-complexity and high-performance cell ID detection schemes for cellular communication systems. The first one, called real-correlation multiple differential detection (RMDD), derived from our previous work on cell ID detection called CERCD method, has much less complex multiplication operations while maintains the same performance.(More)
In this work, a signal-to-interference-plus-noise ratio (SINR)-based robust distributed beamforming scheme is proposed for one-way amplify-and-forward (AF) relay systems with multiple user pairs. The proposed scheme obtains its optimal beam vectors by utilizing convex semi-definite programming (SDP) optimization with newly derived bounds for signal and(More)
This works extends our previous work on cell ID detection for OFDM systems to LTE systems. Specifically, we apply our previously proposed three channel-effect resilient cell ID detection (CERCD) methods to the detection of primary synchronization signals (PSS) in 3GPP LTE systems. Simulation results show that CERCD methods still maintains merits of low(More)
