In the following, we present a novel wideband multiple-input, multiple-output (MIMO) channel model, which we refer to as the structured model. The model is based on the eigenvalue decomposition (EVD) of the wideband channel correlation matrix. It does not assume the scatterers at the receiver fade independently of those at the transmitter. It also models correlation between delay bins in the power...
A subspace-based method for detection of spread-spectrum signals is described in this paper that is similar to superresolution algorithms such as MUSIC. Sample vectors of despread symbol data are collected over time to form a correlation matrix, which is decomposed using eigenvalue decomposition (EVD). When using linear phase modulation, the despread symbol data contains multipath peaks that are due...
