There are countless types of off-axis mirror systems. A plane-symmetric system, a classic off-axis system, is relatively low complexity, due to its plane-symmetric property. Although a 3D system is more complicated, it gives us more degrees of freedom to fit in different volumes. In this thesis, we provide a method to design a 3D mirror system. We will start with the introduction of the plane-symmetric wave function and the 3D system as well as their aberration coefficients. Then we will dive into the method of calculating the aberration coefficients to understand the system and the method of designing a 3D system. Because a 3D system aberrations contain both axially and plane-symmetric aberrations, we have our own macro programs written in two different methods to calculate the aberration coefficients of a 3D system. One is adding the aberration coefficients contributed from each surface. The other one is extracting the aberration from the OPD real ray tracing. With those two algorithms and their macros, we are able to pay close attention to the dominant aberrations and release the proper variables for optimization. In this way, we can understand the system and its limitations better and also the trade-off between different aberrations and other system parameters.Type

The IPTN's Airborne Data Relay System (ADReS): A System Concept and the Phase One System ConfigurationBy making use of NC212-200 commuter aircraft as an airborne container, the ADReS, a short for airborne data relay system, had been configured and tested in an experimental status during the year of 1987. A kind of test on EMC, EMI, RFI and telemetry data link were applied to the system. Prior to the IPTN's flight test program in the year of 1988 - 1992, the ADReS is designed not only to receive and to relay the data, but also planed to be able to process the data for quick data analysis purposes on board. This paper describes the ADReS system concept and its experimental status system - the Phase One system configuration.

SPECTRAL EFFICIENCY/BIT ERROR RATE OF FQPSK AND OTHER NON-COHERENT SYSTEMS SUPERIOR TO COHERENT SYSTEMS FOR SMS AND BURSTED TDMA AND CDMA SYSTEMSFor faster acquisition in bursted environments for SMS (Short Messaging Service) and other lower-bit rate applications, non-coherent detection techniques are proposed. Non-Coherent detection demodulators are proposed because faster acquisition capability in bursted environments can result in a reduced amount of preamble bits in the messaging frame, i.e. less overhead, resulting in an effective increase in spectral efficiency. Reducing the preamble can also provide performance enhancement opportunities for Feher Quadrature Phase Shift Keying (FQPSK) [1] and for other systems. The preamble can also be varied to provide for better Bit Error Rate (BER) performance. The lower bit rate environment also gives the opportunity to employ simpler architectures in lieu of preamble modification. Several non-coherent detection alternatives are described.
