In this letter, we employ orthogonal random beam-forming (ORBF) for the worst-case multi-user downlink scenario whereeachuseriswiretappedby one eavesdropper. Two oppor-tunistic scheduling techniques that ensure confidentiality by ex-ploiting multi-user diversity are investigated thefirst technique (optimal) requires limited feedback of the effective signal-to-in-terference ratio (SIR) from all the users

仿真OOK载波调制信号在AWGN信道下的误码率和误比特率性能，并与理论值相比较。 OOK是ASK调制的一个特例，把一个幅度取为0，另一个幅度为非0，就是OOK。(OOK modulation signal simulation in AWGN channel bit error rate and bit error rate performance, and compared with the theoretical value. OOK is a special case of ASK modulation to an amplitude taken as 0, and the other non-zero amplitude is OOK.)
