Simulation results show that our algorithm enforces the adaptability of differential space-frequency modulation to the time delay expansion.Finally, we give our work to reduce the complexity of multiple symbol differential sphere decoding in differential space-time modulation. Through the modification of the enumeration strategy of the search tree in sphere decoding, we significantly reduce the complexity of detection at the expense of little loss on performance.

Based on the Laser Doppler technology, Information technology, Image Recognition and Process tenology, the laser image characteritics of ultra-fine and non-spherical particles are studied. The laser image recognition method based on neural network theory are obtained. The associated hardware and computer software for analysis of the shape characteristics are developed. The shape characteristics of typical particles such as fire smoke particle and carborundum are studied by using such method. The results of this project are useful to develop the new reliable, accurate and rapid experimental diagnoses technology.
