Space-time block codes versus space-frequency block codes
The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004 In wireless broadband systems the available time, frequency and spatial diversity can be exploited using complex space-time-frequency codes. However, in order to retain a flexible scheme with low complexity we prefer a concatenated system where a channel code picks up time and frequency diversity and a simple orthogonal design is used to obtain spatial

CASTRO: A New Compressible Astrophysical Solver. III. Multigroup Radiation Hydrodynamics
, 2012 We present a formulation for multigroup radiation hydrodynamics that is correct to order $O(v/c)$ using the comoving-frame approach and the flux-limited diffusion approximation. We describe a numerical algorithm for solving the system, implemented in the
