We show in the context of a new economic geography model that when labor is heterogenous trade liberalization may lead to industrial agglomeration and inter-regional trade. Labor heterogeneity gives local monopoly power to firms but also Introduces variations in the quality of the job match. Matches are likely to be better when there are more firms and workers in the local market, giving rise to an agglomeration force which can offset the forces against, trade costs and the erosion of monopoly power. We derive analytically a robust agglomeration equilibrium and illustrate its properties with numerical simulations

Following chapter Introduces the mobile communication, gives a short history of wireless communication evolution, and highlights some application scenarios predestined for the use of mobile devices. Cellular and wireless based systems related to different generations of mobile communication, including GSM, IS-95, PHS, AMPS, D-AMPS, cdma2000 and WCDMA are also described by this Chapter. Much attention in this chapter is given to express the wireless based networks, such as Wi-Fi and WiBro/WiMax, and wireless broadcasting systems, including DMB, DVB-H, and ISDB-T. We conclude the chapter with the future vision of mobile communication evolution

In this first part of the book the Vienna Link Level (LL) Simulators are described. The first chapter provides basics of LL simulations, Introduces the most common variables and parameters as well as the transceiver structures that are applied in Long-Term Evolution (LTE) and Long-Term Evolution-Advanced (LTEA). We focus here mostly on the Downlink (DL) of LTE as most results reported in later chapters are related to DL transmissions.

CAN總線是汽車上應(yīng)用最廣泛的車載網(wǎng)絡(luò)總線,具有實(shí)時(shí)性強(qiáng)、可靠性高、成本低等優(yōu)點(diǎn)。鑒于此,介紹了一種利用飛思卡爾系列單片機(jī)MC9S12XS128作為控制器,利用其內(nèi)部的MSCAN模塊、CAN收發(fā)器TJA1040等外圍元件進(jìn)行CAN總線通信節(jié)點(diǎn)設(shè)計(jì)。該設(shè)計(jì)能夠?qū)崿F(xiàn)CAN總線數(shù)據(jù)的發(fā)送與接收,可應(yīng)用于汽車及其他各種CAN總線通信系統(tǒng)。CAN bus is the most widely used on-board network bus in automobiles. It has the advantages of realtime, high reliability and low cost. In view of this,this paper Introduces the design of CAN bus communication node by using Freescale MC9S12XS128 as controller,using its internal MSCAN module,CAN transceiver TJA1040 and other peripheral components. This design can realize the sending and receiving of CAN bus data,and can be used in automobile and other CAN bus communication systems.
