It shows that proper square root raised cosine pulse shaping filter can improve the error performance of data transmis.

The correlative coding was equivalent to a pulse shaping filter after inverse fast fourier transform (IFFT).

Inter-symbol interference(ISI) and frequency width expanding can be avoided by pulse shaping technique in most communication system.

A new method to generate orthogonal UWB shape impulses is proposed based on the eigenvector of hermitian matrix and chirp signal,and the desired shape impulses have been given.

Based on traditional MHD system and modern MHD,the high power impulse forming and transmitting technique was discussed,the transform technique and implementing circuits of the high power multiple impulses from the single low voltage impulse was investigated,the experimental result was given and the key implementing the system was expounded.

The monitors were installed on water transmission line and pulse forming line.

In order to develop high power ultrawide band technology, the principle of the pulse forming line and the DBD are used to suppress the output waveform of the SOS pulse source, and the experiment results are presented: the pulse with the peak power of 450 MW, pulse duration of 6 ns is compressed into the pulse with the peak power of ~1 GW, pulse width ~1.

A compact output switch for a water pulse forming line(PFL) e-beam accelerator was designed.

Design of a Spiral PFL Based on Tesla;

Three PFLs were serially triggered to form a 3-pulse and a sequence of 3-pulse was produced along the same time axis.

Based on a combination of pulse transformer and distributed electrical parameter pulse forming line(PFL),a high power pulse generating and forming technology is introduced.
