Abstract
A receiver estimates a vector of emitted symbols over a MIMO transmission channel which are emitted by a emitting antennas. The receiver receives a vector of received symbols on receiving antennas. Estimation of the vector of emitted symbols is made by calculating a metric associated with a criterion for each vector of a subset of all possible vectors of emitted symbols and selecting an estimation for said vector of emitted symbol as the vector of emitted symbols among said subset which minimizes said metric.
Claims15
A method for estimating a vector of emitted symbols over a MIMO transmission channel emitted by a first plurality of emitting antennas, comprising:
- receiving a vector of received symbols on a second plurality of receiving antennas;
- estimating said vector of emitted symbols by:
- calculating a metric associated with a criterion for each vector of a subset of all possible vectors of emitted symbols;
- and
- selecting an estimation for said vector of emitted symbol as the vector of emitted symbols among said subset which minimizes said metric.
A receiver adapted for estimating a vector of emitted symbols over a MIMO transmission channel emitted by a first plurality of emitting antennas, comprising:
- a receiving circuit configured to receive a vector of received symbols on a second plurality of receiving antennas;
- a processing circuit configured to estimate said vector of emitted symbols by calculating a metric associated with a criterion for each vector of a subset of all possible vectors of emitted symbols and selecting an estimation for said vector of emitted symbol as the vector of emitted symbols among said subset which minimizes said metric.
