Abstract: Many attempts have been carried out to overcome the bottleneck of test data bandwidth between the tester and the chip in the concept of combining BIST and test data compression. In this paper we present a new test data-compression scheme that is a hybrid approach between external testing and Built-In Self-Test (BIST). The proposed approach is based on Low-Power (LP) programmable generator capable of producing.......

Abstract: Advances in the areas of image coding have generated a growing interest in discrete transforms. The demand of high quality with a limited use of computational resources and improved cost benefits has lead to experimentation with transform coding methods. This project deals with Discrete Tchebichef Transform (DTT) which is a polynomial-based orthogonal transform. Image quality measures that span both the subjective and objective evaluation techniques are computed for the compressed images and the results are analyzed by taking the statistical properties of the images into account......

Abstract: The project presents a test pattern compression method for circuits with a high number of parallel scan chains .It reduces test time while it keeps hardware overhead low. The decompression method is based on the continuous LFSR reseeding that is used in such a way that it enables LFSR lockout escaping within a small number of clock cycles. It requires a separate controlling of the LFSR de-compressor and the scan chain clock input......

Abstract: This project focuses on high throughput and lower complexity using MIMO SC-FDMA detectors. In LTE SC-FDMA is used in the uplink, which saves power in mobile devices. Beam forming is a technique that transmits the input at different angles. Diversity in the MIMO transmits the input signal and anyone of the output received which is more similar to the transmitted signal. Thus the quality of service is improved by MIMO technique...........

Abstract: This brief presents a power architecture for the design of two dimensional median filter .Receiving an input sample and generating a median output at each machine cycle. Sorting method used. The power consumption is reduced by decreasing the number of signal transitions in the circuit. This can be done by keeping the stored samples immobile in the window through the use of token ring in our architecture .Power consumption ,Area, and complexity were successfully reduced.

In addition to that a PI controller is simulated with RL and IM as its loads with their corresponding THD's are simulated in Matlab.

Abstract: A novel technique to enhance the robustness of space–frequency block coded (SFBC) orthogonal frequency-division multiplexing (OFDM) systems. The proposed system shapes the channel matrix of a frequency-selective fading channel into a piecewise flat--fading over each block of two adjacent subcarriers. Analytical and simulation results show that the proposed scheme substantially outperforms the conventional SFBC in frequency-selective fading channels, which assumes that the channel parameters are equal over the duration of the codeword...........
