发明名称 COMMUNICATIONS METHODS, APPARATUS AND COMPUTER PROGRAMS PRODUCTS FOR CHANNEL CHARACTERIZATION
摘要 <p>A communications signal is processed to determine a proportionality relationship between a gain of a first channel (e.g., a pilot channel) and a gain of a second channel (e.g., a traffic channel) from a model of the first channel and information recovered from the second channel according to the model of the first channel. Symbol estimates may be generated from the information received over the second channel based on the determined proportionality relationship. In some embodiments, a gain multiplier may be estimated from information received over the second channel, a channel estimate for the first channel and a noise estimate for the first channel, for example, by generating despread values from the information received over the second channel, processing the despread values according to the channel estimate to generate symbol estimates, and generating the estimate of the gain multiplier from the noise estimate and the symbol estimates. Methods, apparatus and computer program products are provided.</p>
