A Hybrid Single-Carrier/Multicarrier Transmission Scheme with Power Allocation
We propose a flexible transmission scheme which easily allows to switch between cyclic-prefixed single-carrier (CP-SC) and cyclicprefixed multicarrier (CP-MC) transmissions. This scheme takes advantage of the best characteristic of each scheme, namely, the low peak-to-average power ratio (PAPR) of the CP-SC scheme and the robustness to channel selectivity of the CP-MC scheme. Moreover, we deriv...
متن کاملAn Unequal Power Allocation Scheme for JPEG Image Transmission
With the introduction of high data rates in the emerging wireless standards, real-time multimedia communication is becoming common in wireless communication systems. The need for efficient joint source-channel coding (JSCC) and power optimization is growing as these new multimedia services, especially images and videos are introduced in commercial wireless communication systems. These technique...
متن کاملThreshold-based hybrid relay selection and power allocation scheme
To minimize total transmit power in a system while guaranteeing the outage probability at the same time in a cooperative system, we propose and analyse two threshold-based hybrid relay selection and power allocation schemes for a threenode cooperative relaying system. They are designated as: the hybrid amplify-direct-forward relaying (HADF) and incremental hybrid decode-direct-forward relaying ...
متن کاملImage transmission over OFDM channel with rate allocation scheme and minimum peak-toaverage power ratio
This paper proposes new scheme for efficient rate allocation in conjunction with reducing peak-to-average power ratio (PAPR) in orthogonal frequency-division multiplexing (OFDM) systems. Modification of the set partitioning in hierarchical trees (SPIHT) image coder is proposed to generate four different groups of bit-stream relative to its significances. The significant bits, the sign bits, the...
متن کاملMulti-objective Optimization of Hybrid Electric Vehicle Equipped with Power-split Continuously Variable Transmission
This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....
