Abstract
A method voting multiple messages begins with a communication unit (111) transmitting (301) a message. At each of a plurality of sites, the message is received (303) and decoded (305) such that a minimized metric is computed and decoded message is extracted from the message. The minimized metric is adjusted (307), producing an adjusted metric. Each of the plurality of sites transports (309) its decoded message and its adjusted metric to a comparator. The comparator receives (311) selecting the decoded message and the adjusted metric from each of the plurality of sites, compares (313) selecting the adjusted metric from each of the plurality of sites and finds an optimal adjusted metric. The decoded message associated with the optimal adjusted metric is then selected (315).
Claims23
In a system comprising a comparator and a plurality of sites, a method comprising the steps of:
- at each of a plurality of sites:
- receiving a message;
- decoding the message such that a minimized metric is computed and a decoded message is extracted from the message;
- adjusting the minimized metric, producing an adjusted metric;
- and
- transporting the decoded message and the adjusted metric to the comparator.
In a system comprising a comparator and a plurality of sites a method comprising the steps of:
- transmitting, by a communication unit, a message;
- at each of a plurality of sites:
- receiving the message;
- decoding the message such that a minimized metric is computed and a decoded message is extracted from the message;
- and
- transporting the decoded message and the minimized metric to the comparator.
An apparatus comprising:
- a receiver for receiving a message;
- a trellis decoder, operably coupled to the receiver and constructed and arranged to output decoded information from the message and compute a minimized metric;
- and
- an adjuster, operably coupled to the trellis decoder and constructed and arranged to provide an adjusted metric from the minimized metric, which adjusted metric compensates for receiver distortion on strong signals and efficiently indicates signal quality of the message.
A method comprising the steps of:
- A) transmitting, by a communication unit, a message;
- B) at each of a plurality of sites:

- C) at the comparator:
- receiving the decoded message and the adjusted metric from each of the plurality of sites;
- comparing the adjusted metric from each of the plurality of sites and finding an optimal adjusted metric;
- and
- selecting the decoded message associated with the optimal adjusted metric.
