A Comparison of Frequency Domain Equalization in Underwater Acoustic Single Carrier System

چکیده
Abstract Recent research has indicated that single carrier frequency domain equalization (SC-FDE) is an attractive technology for underwater acoustic communications. Because it does not have the drawbacks of OFDM systems such as large peak-to-average ratio and the sensitivity to carrier frequency offsets. In this paper, three kinds of frequency domain equalization schemes were compared in the underwater acoustic SC communication system. Simulation results showed that the H-DFE method achieved a much lower bit-error-rate performance than MMSE and ZF schemes. Further, the results in real underwater acoustic channels also proved this conclusion.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
متن کاملSingle Carrier with Frequency Domain Equalization for Synthetic Aperture Underwater Acoustic Communications
Phase-coherent underwater acoustic (UWA) communication systems typically employ multiple hydrophones in the receiver to achieve spatial diversity gain. However, small underwater platforms can only carry a single transducer which can not provide spatial diversity gain. In this paper, we propose single-carrier with frequency domain equalization (SC-FDE) for phase-coherent synthetic aperture acous...

Orthogonal signal-division multiplexing (OSDM) is a newly emerged modulation scheme which provides a generalized framework unifying conventional orthogonal frequency-division multiplexing (OFDM) and single-carrier frequency domain equalization. In this letter, a space-frequency block coding (SFBC) scheme based on OSDM is proposed for time-varying underwater acoustic channels. The receiver proce...

Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...

An UWA communication system that uses coherent pseudorandom-phase carrier COFDA4 modulation is presented. The system shares the advantages of the correlating receiver of the direct sequence spread spectrum system and COFDkt modulation. A feature of the new system is the use of a pseudo-random Gaussian noise signal as a channel sounding probe to measure the complex channel transfer jimction for ...
