  channel
Aliasing error bounds are derived for one- and two-channel sampling series analogous to the Whittaker-Kotel'nikov-Shannon series, and for the multi-band sampling series, and a "derivative" extension of it, due to Dodson, Beaty, et al.
      
Aliasing in the one-channel case is shown to arise from a transformation with similarities to a projection.

Performance Analysis of LDPC on Rician Fading Channels
      
This paper analyzes and simulates the performance of irregular low-density parity check (LDPC) codes on Rician fading channels.
      
The authors also modified the brief propagation decoding algorithm, proved the symmetry and showed the stability conditions of the channels, and calculated the Shannon limits on Rician channels in this paper.
      
Therefore, the performance of LDPC is also very effective on all kinds of channels, including the Rician kind.

Test investigation on hydraulic losses in the discharge passage of an axial-flow pump
      
In a discharge passage with a guide blade discharge circulation and secondary flow because of bend pipe, the flow in a 1-channel discharge passage of an axial flow pump is a complicated spiral flow.
      
For a 2-channel passage, the discharge in the left channel is bigger than that in the right, and the passage hydraulic losses are abnormal.
      
In this study, the section current energy of the passage is accurately measured and determined with a 5-hole probe.
      
The results indicate that the passage hydraulic losses are not proportional to the flow discharge.

A study on the realization of the stability of decentralized control for large-scale systems by one dimension output feedback is made. The state model and structure model for decentralized control with output feedback of one dimension are given. Based on the two models, the admissible theorem of pole assignment and the theorem of one dimension feedback are proposed. The conditions for the existence of the proportional path and the relevant computational formula are also derived.

For gas flow at high temperature and high speed in MHD-channel, a method of measuring gas velocity without physical contact is discussed in this paper. The random perturbations which exist in MHD-channel are used as informations to measure the speed of gas flow in channel. Based upon the principle of correlation of random signals we have constructed an equipment to measure the difference of time between two measuring points. In the paper the correlative principle of measuring speed is explained and the block diagram is given. For another equipment which measures the average difference of time without correlation, the block diagram and circuit diagram are given in detail. The measured results and thc analysis of errors are also given.

This paper briefly introduces the flying spot scanner of the "789" model of Optical Character Recognition system developed in Futan University. A method of matrix scanning with a high resolution flying spot tube is adopted in the scanner. It has the advantages of high speed and flexible control. There are also equipments of aperture correction, astigmatism correction, concentric correction, dynamic focusing, automatic brightness adjustment and so on in the scanner; so that it can scan a rather large area with high resolution, great precision, good signal/noise ratio and good stability. The system of video signal quantization includes an automatic threshold-adaptive circuit which can be adapted to the scanned documents of poor printing quality and varible darkness of characters. The signal reception system con- tains two channels: the red and black channels. Using the colour selection circuit with the combination of "S curve transformation" and "time logical circuit", it can distinguish between red and black characters. With the documents attaching to the transporting belt by pumping out the air and step-by-step document transporting me- chanism, the documents of convolution type can be effectively transported. In conclu- sion, this scanner system is a opto-electronic converter with flexible control, wide range of adaptation, high resolution, great precision and high scanning speed.
