We present a novel class of space time trellis codes based on super quasi-orthogonal space time codes for a reconfigurable antenna system. We call them space time state trellis codes (STSTCs). We design for 4 trellis states and both 2 and 4 branch trellis structures for BPSK and QPSK constellations. The proposed codes take advantage of the additional(More)
It is known that the performance of limited feedback precoding systems depends on the size of the codebook, determined by the number of feedback bits. Increasing the number of feedback bits improves performance. However, this in turn requires a significant increase in the control channel bandwidth. The goal of the proposed reconfigurable antenna codebook(More)
A novel adaptive video object tracking algorithm is proposed using intensity based and feature based techniques which results in improved reliability and at the same time it aims to reduce computational complexity. This is achieved by intelligently combining SIFT and BMA and making it adaptive to the speed of the moving object. Tracking frame by frame using(More)
