jpeg_encode+decoderhojoon
This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.

OFDM is one of the best physical-layer candidates
for cognitive radio (CR) systems, but rectangular pulse shaping
gives rise to large spectrum sidelobes and interferes with the
licensed user on the adjacent band. In this paper, an approach
is derived based on the signal continuity to measure the spectral
decay rate of the shaping pulse for OFDM.
