Overview Spacecraft data processing requires microcomputers and interfaces that are functionally similar to desktop systems However, space systems require: - Low power, volume, and mass High reliability and fault tolerance

Transmit Gain Optimization for Space Time block Coding Wireless Systems with Co-channel Interference Nevio benvenuto and Stefano Tomasin Dipartimento di Elettronica e Informatica, Universita di Padova

Slide 14.1.1 Elements of ooP Last time we introduced the idea of object oriented systems Today, we want to build on those basics, looking at how we can expand object-oriented systems to deal with hierarchies of objects, to leverage the commonality of methods between

Iterative Receivers for Space-time Block Coded OFDM Systems in Dispersive Fading channels Ben Lu, Xiaodong Wan Ye( Geoffrey)Li Department of Electrical Engineering School of Electrical and Computer Engineering Texas a&M Universit

Improving performance of coherent coded It can be shown that if the channel estimates are perfect(a1=a1, a2 OFDM systems using space time transmit a2)diversity can be achieved

The role of abstractions In this lecture, we are going to look at a very different style of creating large systems, a style called object oriented programming. This style focuses on breaking systems up in a different manner than those we have seen before To set the stage for this, we are first going to return to the notion of
