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).

Timer_key_1602
说明： 利用MSP430单片机实现5分钟倒计时。用Timer_A实现1s定时，4位共阳型数码管显示时间，显示格式为：“x-xx”，分别代表“分”、“十秒”和“秒”。每隔1s，倒计时器的时间减1，倒计时从4分59秒开始计时，至0分0秒结束，停止计时。(MSP430 microcontroller is used to realize 5 minute countdown. Timer_A is used to realize 1s timing and 4-bit common-sun digital tube display time. The display format is "x-x x", representing "minutes", "ten seconds" and "seconds" respectively. Every 1s, the countdown time is reduced by 1. The countdown time starts at 4:59 seconds and ends at 0:0 seconds.)
