各态历经

Under the assumption that the channel state information was available only at the receiver,the capacity of MIMO systems in Rayleigh fading channel was investigated on the basis of information theory. Three special expressions for the MIMO capacity over ergodic flat fading channel were derived.An asymptotic formula for MIMO systems with equal number of transmit and receive antennas in small SNR was also given. Simulation results show that this approximation is relatively accurate.

Then I make the simulations on the ergodic and outage capacity in many cases, on the influence of the k-factor on ergodic capacity, and on the cumulative distribution function of the information rate of a flat fading MIMO channel in water-pouring cases. Then I make analysis of all the simulation results.

After lift curfew the "authoritarian- democracy" of political transformation process, the government pushes a series of political reform, the Taiwan politics enters the period of liberalism, democratization and ethnicism , the elections also affect the development of the party politics, changing the type of the Taiwan party politics, the political liberalism all reduced people to express their ideals cost in the meantime, as a result helped aborigines movements .The aborigines movements starts from aborigine society movement to aborigines' movements, till the movement of reconstruction of the subjective in each tribe, In such situation, the multiculturalism becomes the new direction of the Taiwanese aborigines policy.

研究结果发现随著解严后从「威权—民主」的政治转型过程，政府推动一连串政治改革，台湾政治进入自由化、民主化与族群化时期，各类选举也牵动政党政治的发展，改变台湾政党政治的型态，同时政治自由化均降低了人民表达其意识形态、观念、理想的成本，因而促成原住民族运动在内的政治、社会运动风潮，原住民运动历经从原住民社会运动到原住民族运动到各民族的主体重建运动等历程，就是在这样的政治发展情势与原住民族运动压力下，多元文化主义的原住民族政策就成为台湾原住民族政策的新方向。
