Digital Modulation RRC filters are implemented in the base band as a digital filter. filters (BWDLF) can be used very favourably as pulse shaping filters in digital communications. A new approach, at least in this context, is presented, how to (currently on leave from the Dept. of Communications, Vienna University of Technology) Keywords: OFDM, pulse shaping filter, Weyl-Heisenberg frames.

• Pulse shaping fulﬁls two purposes – limit the transmission bandwidth BT so it ﬁts in channel bandwidth B, and – enable to recover the correct sample values of transmitted symbols • Such a pulse shaping r(t) = g(−t)⋆c(t)⋆ g(t) is called a Nyquist system 1. (Inﬁnite) sinc has a (baseband) bandwidth BT = fs/2, (inﬁnite) raised cosine

Such a system comprises an analog section (fig 1a) and a digital section (fig 1b). Fig 1a,b Fig 2 In the analog section, a current pulse produced by detector is integrated on a feedback capacitor of a charge sensitive preamplifier which produces step-like or slow decaying (50 usec) exponential pulse. Bandwidth (BW) is one of the most crucial resources in the communication industry.

However, its use in space communication is still relatively new. This will possibly change as the crowding of the frequency spectrum used in the space communication becomes a problem.
