One of the multiple advantages of communicating through MIMO
systems is their inherent ability to provide flexible configurations.
Following this line of thought, in this paper we present a generic
framework to study the degrees of freedom in the design of MIMQ
communication systems (e.g.: code length, number of multiplexed
streams, or receiver structure). Precisely, we focus our efforts to
bridge the gap between the design of MIMO systems with full and
no channel state information at the transmitter side and also with
different complexiry degrees at ihe receiver side. For instance, we
can establish a trade-off, not only between the achievable rates and
the diversity or beamforming gains, but also between the rate and
the robustness to uncertainties in the channel state information. |
