  This paper presents a 3-D statistical channel model of the impulse response
with small-scale spatially correlated random coefficients for multi-element
transmitter and receiver antenna arrays, derived using the physically-based
time cluster - spatial lobe (TCSL) clustering scheme. The small-scale
properties of multipath amplitudes are modeled based on 28 GHz outdoor
millimeter-wave small-scale local area channel measurements. The wideband
channel capacity is evaluated by considering measurement-based
Rician-distributed voltage amplitudes, and the spatial autocorrelation of
multipath amplitudes for each pair of transmitter and receiver antenna
elements. Results indicate that Rician channels may exhibit equal or possibly
greater capacity compared to Rayleigh channels, depending on the number of
antennas.
