Design of Secure and Reliable MU-MIMO Transceiver System for Vehicular Networks

Abstract

MU-MIMO (Multi-User MIMO) has been a promising technique for vehicular networks to achieve faster communication. Conventional MU-MIMO transceiver is designed with One-dimensional (1-D) improper modulation schemes such as Binary Phase Shift Keying (BPSK) and Multilevel Amplitude Shift Keying (M-ASK) failed to yield standard ABER (average bit error rate). To achieve high reliability, a novel MU-MIMO uplink transceiver system is designed under PAPC (Per-Antenna Power Constraint) by assuming perfect and imperfect channel state information (CSI). MIMO communication channels are perceptible.Hence, security of the proposed system is improved by novel pseudorandom key generation technique using randomized synthetic colour image. Analytical design for proposed systems is carried and simulated for various p-norm constraints. Simulation results show higher reliability and security than the existing system. It also satisfies the linearity constraint of a power amplifier, which makes the system more suitable for practical applications.

Optimal Tracking of QR Inspired LEA Using Particle Filter for Secured Visual MIMO Communication Based Vehicular Network

“…It is observed that the proposed LFSR based key generation technique has a larger key size when compared to the existing technique ( [32,33]). Although the key size in [34] is larger, the strength of the algorithm is moderate indicated by its lower-key generation time when compared to the proposed technique. The key space is used to determine the strength of the generated key over brute force attacks.…”

“…Moreover, the performance of the proposed security algorithm is compared with the existing techniques [32][33][34]. All these techniques are applied to a single random image to make uniform test conditions.…”

“…A key generation algorithm that generates a considerably large key provides better security. A random pixel value-based color image is used for key generation [32][33][34]. Bit sequences are generated from red, green, and blue planes of the color image.…”

“…Additionally, a histogram of the image is calculated, and its peak value is used to extract the key from the generated bit sequence [33]. Another approach uses the LSB to MSB to generate twenty-four sequences, and the randomness property is used to select the key [34]. A similar approach has been proposed in this work with higher computational complexity leading to more key strength.…”

Comparative and QoS Performance Analysis of Terrestrial-aerial Platforms-satellites Systems for Temporary Events

“…It has been suggested to consider the use of either smart or multiple antenna technology to improve performance. Moreover, because of the Alamouti's scheme MIMO antenna technology is very similar to smart antenna technology and is one of the most efficient leading innovations in wireless systems for maximum capacity, improved QoS and coverage extension range [52,53,74]. The effect of MIMO antennas on near-space solar-powered platforms performance and capacity is discussed in [54][55][56], where it is argued that the antenna gain has to be optimized, otherwise, user ends will experience weak radio across a distance of many miles.…”
