Direct-Mapping-Based MIMO-FBMC Underwater Acoustic Communication Architecture for Multimedia Signals

Abstract

In this paper, a direct-mapping (DM)-based multi-input multi-output (MIMO) filter bank multi-carrier (FBMC) underwater acoustic multimedia communication architecture (UAMCA) is proposed. The proposed DM-based MIMO-FBMC UAMCA is rare and non-obvious in the underwater multimedia communication research topic. The following are integrated into the proposed UAMCA: A 2 × 2 DM transmission mechanism, a (2000, 1000) low-density parity-check code encoder, a power assignment mechanism, an object-composition petrinet mechanism, adaptive binary phase shift keying modulation and 4-offset quadrature amplitude modulation methods. The multimedia signals include voice, image, and data. The DM transmission mechanism in different spatial hardware devices transmits different multimedia packets. The proposed underwater multimedia transmission power allocation algorithm (UMTPAA) is simple, fast, and easy to implement, and the threshold transmission bit error rates (BERs) and real-time requirements for voice, image, and data signals can be achieved using the proposed UMTPAA. The BERs of the multimedia signals, data symbol error rates of the data signals, power saving ratios of the voice, image and data signals, mean square errors of the voice signals, and peak signal-to-noise ratios of the image signals, for the proposed UAMCA with a perfect channel estimation, and channel estimation errors of 5%, 10%, and 20%, respectively, were explored and demonstrated. Simulation results demonstrate that the proposed 2 × 2 DM-based MIMO-FBMC UAMCA is suitable for low power and high speed underwater multimedia sensor networks.

“…A relatively similar technique was implemented in [35] where a direct mapping (DM) based MIMO-FBMC schemes was evaluated for audio and visual data transmission. After the LDPC coding block, the encoded data is transmitted through a 2x2 DM-MIMO scheme.…”

“…Amini et al [ 21 ] developed the filterbank multicarrier (FBMC) technique in doubly dispersive UWA communication channels, and a filterbank prototype filter with a novel cost optimization function to achieve robust signal-to-interference-plus-noise ratios and BER performances. Lin et al [ 22 , 23 ] explored an FBMC-based UWA multimedia communication scheme incorporating single-input single-output (SISO) and DM MIMO transmission mechanisms, (2000, 1000) low-density parity-check (LDPC) encoders, adaptive BPSK or offset quadrature amplitude modulations, and a power assignment method. Sun et al [ 24 ] proposed a filtered multitone (FMT) modulation-based UWA transmission system with low-complexity channel-estimation (CE)-based minimum mean square error (MMSE) turbo equalization, and evaluated the symbol error rate (SER) performances.…”

“…As a result, the heat, produced during this process, was estimated as 2.99 MJ/kg. Lin et al [4] proposed a direct-mapping (DM)-based multi-input multi-output (MIMO) filter bank multi-carrier (FBMC) underwater acoustic multimedia communication architecture (UAMCA). The proposed UAMCA included a 2 × 2 DM transmission mechanism, a (2000, 1000) low-density parity-check code encoder, a power assignment mechanism, an object-composition PetriNet mechanism, adaptive binary phase shift keying modulation and four-offset quadrature amplitude modulation methods.…”
