This paper proposes one kind of multiple moving pedestrians' detection and recognition method in the driver assistance system which is based on the computer vision. Firstly, it uses the improved Consecutive Frames Subtraction to establish a background model for sequence images, and unifies Background Subtraction to carry on an effective detection for… (More)
Employing complex scrambling code (CSC) would introduce quasi-orthogonal address code interference (QOACI) in QPSK I-Q sub-channel, resulting in the decrease of the system capacity, presenting two ameliorated scrambling code schemes, then according to the simulation result, because of the complicated constellations, the system capacity would decline… (More)
It has been proven in this paper that there are two wrong conclusions in smart antenna (SA) application theory for the CDMA system. Here come the two wrong conclusions: 1) only one SA can make multiple CDMA channels transmit directionally on a single carrier simultaneously. 2) SA transmitting beam forming can be realized by amplitude-weighting of… (More)
The paper proves the unusability of smart antenna (SA) which is defined in the TD-SCDMA standard, and so the TD-SCDMA standard should be improved. A reform schema will be given in this paper, which uses CDMA/TDMA respectively in the uplink/downlink channel. In this schema, the SA can still be used in downlink channel. It will give a new life to TD-SCDMA… (More)
High speed downlink packet access (HSDPA) is short of the support of technical and theoretical basis, a feasible method using TDMA in a dedicated CDMA channel to realize HSDPA is given.
The usability of SA is discussed in many aspects, and it is proved that it is impossible to form multi-directional beams for TD-SCDMA signals at the same carrier by a smart antenna (SA).
