1-s2.0-S131915781500097X-main
In this paper we uate the performance of cooperative spectrum sensing (CSS) where
each cognitive radio (CR) employs an improved energy detector (IED) with multiple antennas and
uses selection combining (SC) for detecting the primary user (PU) in noisy and faded sensing (S)
channels. We derive an expression for the probability of false alarm and expressions for probability
of missed detection in non-faded (AWGN) and Rayleigh faded sensing environments in terms of
cumulative distribution function (CDF). Each CR transmits its decision about PU via noisy and
faded reporting (R) channel to fusion center (FC).

Position-Sensorless-Control-for-PM
：针对电动汽车永磁同步电机无位置传感器控制系统，在两相静止坐标系( —B)内将滑模观测器法
与MRAS结合，提出了基于模型参考自适应的滑模观测器，并利用自适应律估计永磁同步电机的转子速度。仿真
和试验表明无位置传感器控制方法是切实可行的。
关键词：电动汽车永磁同步电机无位置传感器控制 自适应滑模观测器(This paper presents a new adaptive slid—mode observer for electric vehicle permanent magnet
synchronous motor(PMSM)sensorless control system，which is combined with the sliding mode observer and model
reference adaptive method in the two—phase stationary reference frame． The speed of PMSM rotor is estimated by
adaptive law．Simulation and experimental results show that the sensol ]ess control method is practical and feasible。
Key words：EV PMSM position sensor]ess control ASMO(adaptive slid—mode observer))
