Abstract
A method and circuitry for channel estimation in a cellular communication system is disclosed. Data is transmitted with variable data transmission rates as a plurality of data symbols over a sequence of time slots. Each time slot has at least a proportion containing data symbols, the proportion being dependent on the data transmission rate. An estimate of the transmission rate is determined and is used in channel estimation so that the channel estimation is based on the proportion of received data symbols.
