the paper I uploaded was submitted in my DSP2 class. The paper discusses the results of the simulation based on the paper of Zatman on "How Narrow is Narrowband?" It investigates the second eigenvalue parameter of the received signal that determines its "narrowbandness". Zatman explains that once the second eigenvalue of the signal autocorrelation matrix rises above the noise floor, the signal BW becomes non-zero.-the paper I uploaded was submitted in my DSP2 class.　The paper discusses the results of the simulation based on the paper of Zatman on "How Narrow is Narrowband?"
