- W2348652729 abstract "To improve spectrum utilization in fading environment,a method is adopted based on the eigenvalue of the autocorrelation matrix of the received signal.This method is based on the random matrix theory,using the ratio from the maximum eigenvalue to the minimum eigenvalue as the test statistic to detect the existence of primary users,so as to improve the spectrum efficiency.Simulations are made respectively based on the BPSK(Binary Phase Shift Keying)and the captured DTV(Digital Television)signals in the Rician fading channel.The results show that the performance of the adopted method is better than the energy detection method in the same fading environment." @default.
