This paper presents a low-complexity design and implementation results of a multi-input multi-output (MIMO) orthogonal frequency division multiplexing (OFDM) symbol detector for high speed wireless LAN (WLAN) systems. The proposed spatial division multiplexing (SDM) symbol detector is designed by HDL and synthesized to gate-level circuits using 0.18um CMOS library. The total gate count for the symbol detector is 238K.

In this paper we describe the design of symbol timing and carrier synchronization algorithms for burst receiver. The demodulator consists of digital down converter, matched filter and synchronization circuits. For symbol timing recovery we use modified Gardner algorithm. And we use decision directed method for carrier phase recovery. For the sake of performance analysis, we compare simulation results with the board implemented by FPGA which is APEX20KE series chip for Alter. The performance results show it works quite well up to the condition that a frequency offset equal to 0.1% of symbol rate.

Kansei engineering or image technology is a tool to analyze relation between product design components and the impression or feeling of human for physical products. This paper attempts to construct the designer\`s aid tool for developing corporate identity(CI) symbol mark based on the hybrid Kansei engineering. It combines the forward Kansei engineering for translating consumer\`s feeling into design components of CI symbol mark and the backward Kansei engineering for evaluating consumer\`s feeling for CI symbol mark. The semantic differential(SD) evaluation experiment is carried out to find the relations between image and design. The backward Kansei engineering system is modelled by fuzzy neural network. This research is expected to contribute to the development of CI symbol mark that correspond to comsumer\`s image.

In the confusion of communication, the monogram is the very important symbol of information communication as the visual language for the identity, which have became gradually the important role as the most excellent competence of the visual message. By study the nature, function and symbolism of a monogram in formative element of symbol design, we have the aims in this study to help the design study groups in this country to develop the korean monogram with a correct understanding of mooogram in the present state of korean monogram.

Symbol mark started with expressing the symbolic form through the long history of human beings, in order to transmit self or group's life and thoughts, and since the Industrial Revolution, symbol mark has beer used for the business activities of enterprise, along with the acquirement of term 'CI'. The symbol mark design of A.E.G, designed by Peter Behrens in 1907 is the onset of symbol mark in the CI concept, and the concept of CI and symbol mark was introduced to our nation in the early of 1970s. Since then, until now, CI has reflected the phase of the times as a key factor of CI, while repeating numerous changes, and recently, it is a state that the expression methods of symbol mark have been varied with the popularization of trend, appealing to emotion in the whole society and culture. Accordingly, this thesis examines the corporate symbol mark through the portfolio of representative CI specializes companies from the introduction period of CI to the present, and analyze the features of the time in order to present the basis of the direction of symbol mark design for the creation of future corporate images.
