Taiwan stock market trend is fast changing. It is affected by not only the individual investors and the three major institutional investors, but also impacted by domestic political and economic situations. Therefore, to precisely grasp the stock market movement, one must build a perfect stock forecast model. In this article, we used a multi-stage optimized(More)
In this paper, a baseband transceiver system, architecture design and verification for WCDMA/HSDPA communications is presented. The proposed receiver consists of a channel estimator for channel estimation and receiver parameter calculation, a carrier synchronization and timing synchronization block for carrier frequency offset and clock offset compensation,(More)
A traditional database methodology has been used in the Indian stock market. Forecasting of the market is not only based on the prices of the stocks but also on other integrated information like socioeconomic factors, prices, politics etc. Changing data format and its behavior requires a new methodology to handle and integrate.

²Information technology such as data mining or text mining, can extract useful data structure from data. But extracted data structure was hardly used in explaining the meaning of data itself. In reality, a laborer can hardly catch any meaningful job information from members of his work group (strong tie) when it comes to changing jobs. However, some of his(More)
This paper presents an efficient and practicable MIMO transceiver in which transmitter antenna selection is applied to minimum mean-squared-error V-BLAST (MMSE V-BLAST) detector and GMD precoding through limited feedback channel. The method compensates the deficiency of the GMD algorithm under ill-conditioned channel and improves the BER performance(More)
