Construction of coherent space time codes from non-coherent ones

In this work, the natural geometric relation between the space time block code design if the channel is unknown at the receiver and its counterpart design if the receiver knows the channel is exploited, In this work, the natural geometric relation between the space time block code design if the channel is unknown at the receiver and its counterpart design if the receiver knows the channel is exploited, to establish an estimate on the corresponding diversities. This leads to a decomposition of code designs and splits the design problem into two complexity reduced sub tasks.
