This thesis analyses parliamentary privilege. The privilege is an ancient parliamentary power. All of countries that have democratized or will soon have democratized provide them by own constitution. The purpose of the parliamentary privilege is to permit members of the legislature to speech freely and express their opinion of political position, and not worry about retaliation on the basis of political motives. The Parliament formulates itself its own rules of procedure and maintains the discipline of parliament itself and so on, in order to ensure that the parliament can independently, freely discharge of its duties and perform its functions. Parliamentary privilege, however, is often misunderstood by popular who believes that the privilege is the special protection of all of the elites of society. That is ironic, because privilege was originally produced as a whole of the protection of Parliament, and it protected members of parliament from the elites at that time. It may be said that parliamentary privilege is a special institutional arrangements based on the principles of democracy. Compared with other

This thesis deals with Experimental Channel Characterisation and its performance limits in real propagation environments. This includes recording of the multidimensional wideband channel matrix by using a Multiple-Input Multiple-Output (MIMO) channel sounder and antenna arrays at both sides of the link. High-resolution parameter estimation is finally applied to characterise the channel in terms of Direction of Departure (DoD), Direction of Arrival (DoA), Time Delay of Arrival (TDoA), and complex polarimetric path weights. The quality of these estimates in “real world ” scenarios is degraded by several impairments of the practical antenna arrays and the measurement system used. The resulting estimation quality limits are investigated in detail by simulations and measurements. The entire processing chain is analysed in terms of possible error sources. To this end, measurement system impairments, antenna array calibration errors as well as limitations of the radio channel model applied by the high-resolution parameter estimation procedure are investigated. Moreover, consequences of using these results to deduce and parameterise geometry based channel models are demonstrated. Propagation measurements give us an antenna dependent description of the radio channel. For the
