Abstract
A communication device is described comprising a receiver configured to receive a receive symbol vector resulting from a transmission of a transmit symbol vector from at least one transmitter to the receiver wherein the transmit symbol vector comprises a plurality of transmit symbols wherein each transmit symbol is associated with a modulation type and a detector configured to determine a detection order for the plurality of transmit symbols based on the modulation types and to determine, for at least one bit of at least one transmit symbol, at least one soft value based on the receive symbol vector according to the detection order.
Claims26
A communication device comprising
- a receiver configured to receive a receive symbol vector resulting from a transmission of a transmit symbol vector from at least one transmitter to the receiver wherein the transmit symbol vector comprises a plurality of transmit symbols wherein each transmit symbol is associated with a modulation type;
- and
- a detector configured to determine a detection order for the plurality of transmit symbols based on the modulation types and to determine, for at least one bit of at least one transmit symbol, at least one soft value based on the receive symbol vector according to the detection order.
A method for signal detection comprising
- receiving a receive symbol vector resulting from a transmission of a transmit symbol vector from at least one transmitter to the receiver wherein the transmit symbol vector comprises a plurality of transmit symbols wherein each transmit symbol is associated with a modulation type;
- determining a detection order for the plurality of transmit symbols based on the modulation types;
- and
- determining, for at least one bit of at least one transmit symbol, at least one soft value based on the receive symbol vector according to the detection order.
A communication device comprising
- a receiver configured to receive a receive symbol vector resulting from a transmission of a transmit symbol vector from at least one transmitter to the receiver wherein the transmit symbol vector comprises a plurality of transmit symbols;
- a first detector configured to determine, for at least one bit of a transmit symbol, a first soft value;
- a second detector, configured to determine, based on the first soft value, a tree pruning criterion and determine, for at least one bit of a transmit symbol, a second soft value using a tree search based on the tree pruning criterion.
