Abstract
A receiver (500) utilizes parameters generated by a Viterbi decoder (530) to determine one of a plurality of coding rates in which user information is transmitted. The receiver (500) combines the parameters in a predetermined manner, the result of which is a detection statistic (dij). By utilizing the detection statistic (dij), the coding rate at which user information is accurately determined.
Claims8
A method of determining coding rate in a receiver implemented in a wireless communication system, the receiver responsive to a communication resource containing user information coded at one of a plurality of coding rates, the method comprising the steps of:
- generating parameters indicative of the likelihood of coding at the plurality of coding rates;
- combining the parameters in a predetermined manner to produce a detection statistic;
- and
- determining the coding rate based on the detection statistic.
A receiver for determining the coding rate of user information transmitted in a wireless communication system, the receiver responsive to a communication resource containing the user information, the user information coded at one of a plurality of coding rates, the receiver comprising:
- a receiver front end which receives and demodulates the communication resource to produce demodulated user information;
- a decoder, coupled to the receiver front end, which decodes the demodulated user information and generates parameters indicative of the likelihood of coding at the plurality of coding rates;
- a processor, coupled to the decoder, for combining the parameters in a predetermined manner to produce a detection statistic and determining the coding rate based on the detection statistic.
