Report and thesis on abnormal crowd detection.

We present a user-scheduling scheme for multiuser multiple-input–multiple-output (MIMO) systems with random unitary beamforming (RUB) in this paper. The new scheme, which is termed as adaptive beam activation based on the conditional best beam index feedback (ABA-CBBI), requires low average feedback load by imposing a feedback threshold on the users’ signal-to-interference-plus-noise ratio (SINR) and suffers less multiuser interference by only activating those beams requested by at least one user.

单径或多径瑞利衰落信道仿真，使用高阶累积量对MPSK信号进行调制识别，考虑雨衰 阴影 和多径影响。( Single path or multipath Rayleigh fading channel simulation, Using high-order cumulants of MPSK signal modulation recognition, Consider shadow rain attenuation and multipath effect.)

本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法,此为咬尾turbo编码算法(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm, this is the tail biting turbo coding algorithm)
