这是一个对通信领域非常先进的空分对址技术(SDMA)的改进实现算法,程序更为健壮,合理-This is a very advanced communications on site air separation technology (SDMA) to improve the algorithm implementation process more robust and reasonable

As a multi-carrier modulation scheme, Orthogonal Frequency Division Multiplexing (OFDM) technique can achieve high data rate in frequency-selective fading channels by splitting a broadband signal into a number of narrowband signals over a number

We formulate a scheduling problem that takes into account different hardware delays experienced by the secondary users (SUs) in a centralized cognitive radio network (CRN) while switching to different frequency bands. We propose a polynomial-time
