the usage of turbochargers in diesel engines has led to the downsizing of the motors as well as usage of the waste gates in turbochargers. any dimensional reduction in turbochargers and appurtenant leads to an enhancement on the performance of internal combustion engines and in environmental problems in terms of aerodynamic, thermodynamic and mechanical specifications for both engines and turbo...
This work investigates the achievable information rate with the state-of-the-art turbo coding and intensity modulation / direct detection for outdoor long-distance free-space optic (FSO) communications. The channel under weak atmospheric turbulence is modeled as a log-normal intensity fading channel where on-off keying makes it look asymmetric. While no effort is made to spectrally match the co...
Turbo expanders are rotary machines which recover energy by the expansion of gas or steam and the transference of it to electrical energy. In the past, these machines were used in reducing-pressure stations of power plants and of big cities. By the development of knowledge, the usage of turbo-expanders in other industries such as gas well has become possible. In this research, at first, the con...
In order to prevent energy waste by throttle valve in gas pressure reducing station of Neka thermal power plant, a turbo-expander with a capacity of 9.8 MW for the power plant was prepared and installed. Due to the absorption of 63 MVAr reactive powers at the moment of turbo-expander starting, resulted in severe voltage drops in the power plant auxiliary service system. In this paper, while pat...
An area and computational-time efficient turbo decoder implementation on a reconfigurable processor is presented. The turbo decoder takes advantage of the latest sliding window algorithms to produce a design with minimal storage requirements as well as offering the ability to configure key system parameters via software. The parameter programmability allows the decoder to be used in a research ...
Since their discovery in 1993, turbo codes have been found to provide excellent performance with relatively low complexity. Turbo codes have been added to the Consultative Committee for Space Data Systems (CCSDS) standards for telemetry channel coding, and turbo encoders are being included in spaceflight hardware and software. This article describes the design of the prototype turbo decoder for...
Turbo-Codes will most likely be employed in future radio systems as a channel coding scheme for highrate data services. However, Turbo-Decoding is a comparatively complex task. To obtain efficient decoder implementations, the system design space has to be explored on multiple levels. In this paper, we span the system design space for Turbo-Codes and describe a method of exploration, while focus...
This paper studies the performance of phase modulation through a fully saturated power amplifier and AWGN channel for broadband wireless systems. A nonlinear model for the fully saturated power amplifier is derived. The equivalent impulse response method is provided to analyze the SNR degradation. Both convolutional code and turbo code are used. The Viterbi decoding and the iterative decoding a...
