The vOICe Learning Edition (exe): The vOICe seeing-with-sound software translates images from a PC camera Web cam into sounds that you hear via your stereo headphones, thus targeting vision substitution applications for the totally blind, and even synthetic vision. The vOICe Learning Edition is a program, which is very useful for the blind people. Some...; Tags: Video Capture, Voice, Vision, vOICe Learning Edition, Strategy, Management; Software downloads 2008-01-10

Generalized 8-PSK for Totally Blind Channel Estimation in OFDM: Channel estimation in OFDM systems can conveniently be done by inserting a stream of pilot symbols at the transmitter and by using FIR interpolation filters at the receiver. Most blind channel estimation approaches are based on higher order statistics and converge slowly, making them unsuitable for mobile environments. Moreover, the...; Tags: Channel Estimation, OFDM, Wireless; White papers

Joint Data Detection and Channel Estimation for OFDM Systems: The paper develops new blind and semi-blind data detectors and channel estimators for Orthogonal Frequency-Division Multiplexing OFDM systems. The data detectors require minimizing a complex, integer quadratic form in the data vector. The semi-blind detector uses both channel correlation and noise variance. The quadratic for the blind detector suffers from...; Tags: Data Detector, OFDM, Wireless; White papers 2006-04-01
Blind Carrier Frequency Offset Estimation in SISO, MIMO, and Multiuser OFDM Systems: Relying on a kurtosis-type criterion, a low-complexity blind carrier frequency offset CFO estimator is developed for orthogonal frequency-division multiplexing OFDM systems. The paper demonstrates analytically how identifiability and performance of this blind CFO estimator depend on the channel's frequency selectivity and the input distribution. The paper shows that this approach...; Tags: MIMO, OFDM, Wireless; White papers 2005-01-01
JNT Association Case Study: The Royal National College for the Blind, Hereford: The Royal National College for the Blind was invited to join the pilot project to connect specialist colleges to JANET, the UK's education and research network. The JANET link now caters for 212 learners across a wide range of ages, including 12 distance learning students. The RNC's mission is to...; Tags: Distance Learning, College, RNC, E-learning, Enterprise Software, Software; Case studies
Blind and Semiblind Spatio-Temporal Diversity for OFDM Systems: Adaptive antenna arrays can be used to improve the performance of Orthogonal Frequency Division Multiplexing systems. They are usually applied in the frequency domain, after the FFT demodulation. In this paper, the selected algorithms are applied in time domain. A blind method is firstly proposed for the maximization of the...; Tags: Algorithm, Method, Domain, OFDM, Engineering, Wireless; White papers
Totally Blind APP Channel Estimation for Mobile OFDM Systems: A new two-dimensional blind channel estimation scheme for coherent detection of OFDM signals in a mobile environment is presented. The channel estimation is based on the A Posteriori Probability APP calculation algorithm. The time-variant channel transfer function is completely recovered without phase ambiguity with no need for any pilot or...; Tags: Mobile, Channel Estimation, Phase Ambiguity Problem, OFDM, Advertising & Promotion, Wireless, Marketing; White papers

Totally Blind Channel Estimation for OFDM on Fast Varying Mobile Radio Channels: A new blind channel estimation scheme for OFDM-systems is proposed based on the ML-principle. By avoiding the use of second- and higher-order statistics, a very fast convergence rate is achieved. A novel approach is also proposed for resolving the phase ambiguity of the blind channel estimate without the need for...; Tags: Georgia Institute Of Technology, Performance, Mobile, Radio, Ambiguity, Channel Estimation, OFDM, Advertising & Promotion, Wireless, Marketing; White papers
Bayesian Blind Parafac Receivers for DS-CDMA Systems: This paper proposes a new Bayesian blind detection/identification algorithm for CDMA system in presence of spatial diversity at the receiver. Such algorithm provides good performance even for short frame length (typically, 10 symbol periods) and for large system load. Furthermore, simulation results show that the proposed method is close to...; Tags: Algorithm, Rice University, Bayesian, Engineering; White papers
The Application of Signal's Cyclostationarity in OFDM Systems: Blind signal processing is one of necessary methods for high data rate communication because no aided data are required, which will bring redundancy. OFDM is an attractive technique for the next generation communication for its many advantages. However, there are many problems in OFDM systems, such as channel estimation and...; Tags: OFDM, Wireless; White papers 2006-04-01

A Comparison of Blind Channel Estimation Schemes for OFDM in Fading Channels: This paper brings together three recently proposed blind detection schemes which are specific to Orthogonal Frequency Division Multiplexing OFDM systems. The aim is to study the performance of these schemes in fading channels and thus give a critical comparison of them in the environment where they are most expected to...; Tags: Algorithm, Singapore, OFDM, Engineering, Performance Management, Wireless, Human Resources, Workforce Management; White papers
RFID Information Grid for Blind Navigation and Wayfinding: This paper describes a navigation and location determination system for the blind using an RFID tag grid.
