Abstract
A data communication network to transmit and/or receive data using soft-decision information is provided. A target access point in a data communication network may compute soft-decision information with respect to information bits corresponding to a transmission symbol, and transmit the computed soft-decision information to a destination device or an access point connected to the destination device. The destination device or the access point connected to the destination device may combine soft-decision information of a plurality of access points, and detect information bits based on the combined soft-decision information.
Claims20
A method of operating a target access point, the method comprising:
- receiving a transmission symbol transmitted by a source device to a destination device;
- computing soft-decision information for a soft decision with respect to information bits corresponding to the transmission symbol;
- detecting the information bits based on the computed soft-decision information;
- and
- transmitting the soft-decision information or the detected information bits to the destination device or an access point connected to the destination device,
- wherein the destination device or the access point connected to the destination device combines the soft-decision information transmitted by each of a plurality of access points.
A method of operating a destination device or an access point connected to the destination device, the method comprising:
- receiving soft-decision information about information bits corresponding to a transmission symbol from a plurality of access points, the transmission symbol being transmitted from a source device to the destination device;
- combining the soft-decision information of the plurality of access points;
- and
- detecting the information bits using the combined soft-decision information.
A method of operating a router, the method comprising:
- receiving soft-decision information about information bits corresponding to a transmission symbol from a plurality of access points or at least one neighbor router, the transmission symbol being transmitted from a source device to a destination device;
- combining soft-decision information of the plurality of access points or the at least one neighbor router;
- and
- transmitting the combined soft-decision information to the destination device or an access point connected to the destination device.
A computer-readable recording medium storing a program to implement an operation of a target access point, comprising instructions to cause a computer to:
- receive a transmission symbol transmitted by a source device to a destination device;
- compute soft-decision information for a soft decision with respect to information bits corresponding to the transmission symbol;
- detect the information bits based on the computed soft-decision information;
- and
- transmit the soft-decision information or the detected information bits to the destination device or an access point connected to the destination device,
- wherein the destination device or the access point connected to the destination device combines the soft-decision information transmitted by each of a plurality of access points.
A communication device of a destination device or an access point connected to the destination device, the communication device comprising:
- a receiving unit to receive soft-decision information about information bits corresponding to a transmission symbol from a plurality of access points, the transmission symbol being transmitted from a source device to the destination device;
- a combining unit to combine the soft-decision information of the plurality of access points;
- a detection unit to detect the information bits using the combined soft-decision information;
- and
- an error check unit to check to find an error in the detected information bits.
