The transmission of information in a block can be modelled with the following equation
where S is the input matrix, H is the channel matrix, \rho is a scalar coefficient that modulates the channel and W is the noise.
DUST encodes the information in a unitary matrix U_n, which is indirectly encoded through a sequence of two S unitary blocks as
If H is full-rank and the channel does not change significantly in the time the two blocks are transmitted. The unitary matrix U can be recovered from the sequence of two received unitary blocks X without! the need to know the channel H as
where the new noise is defined as
