Asymptotic Eigenvalue Moments of Wishart-Type Random Matrix Without Ergodicity in One Channel Realization
Chien-Hwa Hwang
Consider a random matrix whose variance profile is random. This random matrix is ergodic in one channel realization if, for each column and row, the empirical distribution of the s…

Spectrum Sensing in Wideband OFDM Cognitive Radios
Chien-Hwa Hwang, Shih-Chang Chen
In this paper, detection of the primary user (PU) signal in an orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) system is addressed. According to the pr…

Asymptotic Spectral Distribution of Crosscorrelation Matrix in Asynchronous CDMA
Chien-Hwa Hwang
Asymptotic spectral distribution (ASD) of the crosscorrelation matrix is investigated for a random spreading short/long-code asynchronous direct sequence-code division multiple acc…
