An 8-GHz beamforming transmitter IC has been designed in a 130-nm CMOS process. Two power amplifiers with independently controllable phase enable the beamforming. The phases are digitally controllable over the full 360◦ range, which is accomplished by binary weighting of quadrature phase signals in the power amplifiers. The quadrature phase signals are generated by a quadrature voltage controlled
In this paper several rate R = 2/5 convolutional encoding matrices with four states are used to illustrate how unequal error protection can be achieved for the different positions in the code sequences as well as in the information sequences. Free output- and input-distances and active burst output- and input-distances are computed. Typically a single code cannot combine a large free output- or in
Jag har analyserat det konstruktiva sambandet i kursen BIMM60 – examensarbete på masternivå i biomedicin. Kursen är den i sista kursen inom masterutbildningen. Eftersom alla biomedicinstudenter enligt utbildningsplanen även går BIMK30 - examensarbete på kandidatnivå i biomedicin är det viktigt att även beakta progressionen mellan dessa kurser. Jag fann en del brister i det konstruktiva sambandet m
Essential to this paper is the recognition of the "privileged status our culture accords written discourse", which is discussed against the background of "the variety of ways in which we represent our realities" (Chaplin, 1994, p. 277), the power of representations to influence perceptions (Jacob, 1989) and the ever-growing importance of communities of shared meaning (Delanty, 2002). Jenks' argume
