摘要： In a communication system, a method for estimating a transmitted signal is disclosed. A communication signal is received. A delay-power analyzer analyzes the communication signal. A delay spread is then estimated from information obtained from the delay-power analyzer. A new equalizer filter length is determined based on the estimated delay spread. An equalizer is configured to use the new equalizer filter length.

摘要： A method for estimating a transmitted signal. A wireless signal is received that includes a pilot channel and at least one other channel. The wireless signal is processed using a rake receiver front end to provide a plurality of front end outputs. Channel estimation is performed on the plurality of front end outputs to obtain a plurality of channel estimates. The channel estimates are then used to combine the plurality of front end outputs into a combined signal. A transmitted signal is estimated using an equalizer and the combined signal. The equalizer includes a filter with a plurality of taps that are adapted through use of an adaptive algorithm that uses an estimated pilot estimated from the received wireless signal. The pilot channel is transmitted in the wireless signal that included the at least one other channel. The estimated pilot is extracted and provided to the adaptive algorithm.

摘要： Techniques for determining valid (i.e., supported) TFCs from among all configured TFCs for normal and compressed modes. These techniques maintain sufficient historical information such that "TFC qualification" may be accurately performed. In a first scheme, Tx_power_requirement states are maintained for different combinations of each TFC. One combination is applicable for each TFC at each TFC interval, and valid TFCs are determined from applicable combinations in the proper state(s). In a second scheme, two Tx_power_requirement states are maintained for each TFC for the normal and compressed modes. In a third scheme, a single Tx_power_requirement state is maintained for each TFC for both modes based on a particular relative power requirement. In a fourth scheme, Tx_power_requirement states are maintained for a set of relative "bins" that cover the total range of required transmit power for all TFCs. And in a fifth scheme, a set of relative power requirement thresholds are maintained.
