Iterative Estimation in Turbo Equalization Process

Journal of Electrical and Electronics Engineering, 2014
This paper presents the iterative estimation in turbo equalization process. Turbo equalization is the process of reception in which equalization and decoding are done together, not as separate processes. For the equalizer to work properly, it must receive before equalization accurate information about the value of the channel impulse response.

Zak-OTFS and Turbo Signal Processing for Joint Sensing and Communication

CoRR
The Zak-OTFS input/output (I/O) relation is predictable and non-fading when the delay and Doppler periods are greater than the effective channel delay and Doppler spreads, a condition which we refer to as the crystallization condition. The filter taps can simply be read off from the response to a single Zak-OTFS pilot pulsone, and the I/O relation can ...

Simulating the Process of Vertical Tillage with a Turbo-Disc Cultivator for the Territories of Crimea

Engineering technologies and systems
Introduction. A promising means for cultivating the arable layer is vertical tillage using agricultural machinery with disc working tools. This agricultural machinery is used to crush and partially embed plant residues into the soil with minimal soil damage that results in increased yields.

Turbo Processing for Speech Recognition

IEEE Transactions on Cybernetics, 2014
Speech recognition is a classic example of a human/machine interface, typifying many of the difficulties and opportunities of human/machine interaction. In this paper, speech recognition is used as an example of applying turbo processing principles to the general problem of human/machine interface.

Turbo Iterative Signal Processing

2009 IEEE 13th Digital Signal Processing Workshop and 5th IEEE Signal Processing Education Workshop, 2009
A Turbo iterative method for signal processing is proposed. This method is a kind of multi-systems collaborative signal processing through iteration: several independent systems work in rotation, and each system takes feedback information from the other systems as a priori condition.

Turbo processing in transmit antenna diversity systems

Annales Des Telecommunications/Annals of Telecommunications, 2001
We consider turbo-trellis-coded transmission over fading multiple-input-multiple-output (M1M0) channels with transmit diversity using space-time block codes. We give a new view on space-time block codes as a transformation of the fading MIMO channel towards a Gaussian single-input-single-output (siso) channel and provide analytical results on the BER ...

Turbo processing for an OFDM-based MIMO system

IEEE Transactions on Wireless Communications, 2005
We consider improving the overall system performance of an orthogonal frequency-division multiplexing-based multiple-input multiple-output (MIMO) wireless local area network system. We use a combined iterative detection/decoding and channel updating method, referred to herein as turbo processing, to improve performance.

Exploring parallel processing levels in turbo demodulation

2010 6th International Symposium on Turbo Codes & Iterative Information Processing, 2010
Iterative processing in a wireless base-band receiver ensures promising error rate performance at the cost of high processing time for data retrieval. Exploration of parallelism in iterative processes, while maintaining the error rate performance, contributes toward fulfilling the high transmission rate requirements of emerging wireless communication ...
