In this letter we determine the derivative of the mutual information corresponding to bit-interleaved coded modulation systems. The derivative follows as a linear combination of minimum-mean-squared error functions of coded modulation sets. The result finds applications to the analysis of communications systems in the wideband regime and to the design of power allocation over parallel channels.

Interior permanent magnet synchronous motors (IPMSMs) have been widely used as traction in electric vehicles. Finite element analysis is commonly to design IPMSMs but highly time-intensive. To shorten the period for IPMSMs, various surrogate models constructed predict relevant characteristics, and they optimization of IPMSM geometry. However, date, no able accurately characteristics over wide s...

The diversity order is crucial for the performance of communication systems over Fading Channels. It has been shown by Zehavi that the diversity and hence performance of coded modulation over fading channels can be improved by bitwise interleaving at the encoder output, and by using an appropriate soft decision metric as an input t o the Viterbi decoder. A related approach is coordinate interle...

Photoplethysmography (PPG) devices are widely used for monitoring cardiovascular function. However, these devices require skin contact, which restricts their use to at-rest short-term monitoring. Photoplethysmographic imaging (PPGI) has been recently proposed as a non-contact monitoring alternative by measuring blood pulse signals across a spatial region of interest. Existing systems operate in...

in this project, first we introduced a general rule for the design of drying processes and then, we have applied microsoft excel for this purpose. belt dryer is one of the most common dryers in the food industry. in this study, our aim was to process carrot by this dryer. we optimized the target function (total annual cost or tac) and investigated the influence of design variables on this targe...

Images or videos are generally coded before transmission, and they can be either non-scalable coded or scalable coded, which can be further classified into fine-scalable coded and coarse-scalable coded. In this paper, we focus on delivery of fine-scalable coded content. The objective of our work is to design algorithms to optimize the quality of finescalable coded images or videos on peer-to-pe...

Full digital design with coded excitation for Doppler ultrasound system is proposed to offer full-depth examination, and to improve system SNR and penetration. The experimental platform is developed based on a Doppler phantom and a transcranial Doppler system. Raw radiofrequency signals are collected from the Doppler phantom using the transcranial Doppler system, which alternately transmits non...

A design method for recursive space-time trellis codes and parallel concatenated space-time turbo coded modulation was recently proposed as a new framework for building optimized, low-complexity, large equivalent constraint-length space-time trellis codes. In this paper the distance spectrum interpretation of the space-time turbo coded modulation is introduced to evaluate the union bound on the...

Cryptography and Network Security in high speed networks demands for specialized hardware in order to match up with the network speed. These hardware modules are being realized using reconfigurable FPGA technology to support heavy computation. Our work is mainly based on designing an efficient architecture for a cryptographic module and a network intrusion detection system for a high speed netw...
