摘要:
A radio receiver apparatus includes a demodulator configured to output a decision variable indicative of a binary indicator signaled from a transmitter over a channel to the radio receiver apparatus. The radio receiver apparatus further includes a noise power estimator configured to generate noise power estimates indicative of noise experienced at the radio receiver apparatus. A binary indicator estimator is provided to generate an estimated binary indicator based on the decision variable and the noise power estimates.
