摘要:
The present invention relates to a demodulation method for enhancing decoding performance of information bits in a constant-amplitude multi-code biorthogonal modulation communication system, which performs encoding to cause the level of a transmission symbol to be constant. In the demodulation method of the present invention, a demodulator demodulates the received signal, the demodulator having four blocks. C (c≦2k, k is the number of information bits) bit streams with higher correlation values in descending order are selected and combined among demodulated bit streams to establish c4 bit stream candidates. A parity check is performed with respect to the c4 bit stream candidates, a candidate group having a maximal sum of correlation values is selected among candidate groups in which any error is not generated at the parity check. A bit stream corresponding to the selected candidate group is determined to be an output of a receiver. If a hypothesis in which any error is not generated does not exist, a bit stream determined using a maximum correlation value with respect to each of the blocks is output. According to the present invention, there is an advantage in that an error in reception bits can be detected or corrected, thus improving reception performance.

A method for in-situ polycrystalline thin film growth is provided. A catalyst enhanced chemical vapor deposition (CECVD) apparatus is used to grow the polycrystalline silicon thin film. No subsequent annealing or dehydrogenating process is needed. The method comprises exhausting a chamber to form a vacuum chamber, and then purging vacuum chamber and introducing a catalyst. A substrate is then placed in the vacuum chamber and reaction gas is injected into the chamber. The reaction gas reacts with the catalyst in the chamber to grow a polycrystalline thin film on the substrate. The inventive method reduces processing time and production cost and can be used to fabricate larger devices due to the elimination of bulky annealing equipment.

Disclosed herein is a device and method for generating a thumbnail Joint Picture Experts group (JPEG) image and a medium for storing the thumbnail JPEG. The device includes a scaler, first frame memory, a JPEG signal processing unit, second frame memory and a memory control unit. The scaler scales an input image to a predetermined size to output an image for main JPEG, and scales the input image to a size smaller than the image for main JPEG and to outputs a thumbnail JPEG image. The first frame memory stores the thumbnail JPEG image. The JPEG signal processing unit performs JPEG encoding on the image for main JPEG and the thumbnail JPEG image, and outputs a main JPEG image and a thumbnail JPEG image. The second frame memory stores the main JPEG image and the thumbnail JPEG image. The memory control unit transfers the thumbnail JPEG image to the first frame memory, and transfers the main JPEG image and the thumbnail JPEG image to the second frame memory. Additionally, the JPEG signal processing unit receives the main JPEG image and the thumbnail JPEG image stored in the second frame memory, and outputs the main JPEG image and the thumbnail JPEG image as a single JPEG file.
