Abstract: 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.

Abstract: In a wireless communication system, a method for estimating a transmitted signal is disclosed. A wireless signal is received that includes a pilot channel and at least one other channel. A transmitted signal is estimated using an equalizer and the received wireless signal. Taps of a filter of the equalizer are adapted through use of a channel estimate. The channel estimate is calculated from the pilot channel. The pilot channel and the at least one other channel are separated.

Abstract: A method for improving channel estimation in a wireless communication system is disclosed. A wireless signal that includes a plurality of multipath components is received. N channel estimates are then obtained, where N is any positive integer greater than one. Each channel estimate of the N channel estimates corresponds to a different multipath component of the plurality of multipath components. The effects of interference between the plurality of multipath components on the N channel estimates is then reduced.

Abstract: 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.

Abstract: 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 output. 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.

Abstract: Method and apparatus for reducing interference in a wireless communication system when the source of interference is a deterministic component of the system. In one embodiment, the receiver weights the transmitters according to when the source of interference is transmitted. Further, the transmitter may employ power boosting to overcome the source of interference. In one embodiment, a W-CDMA system transmits a sync channel concurrently with physical channels, wherein the sync channel is not orthogonal to the physical channels. The receiver may cancel the sync channel when receiving control or data information. Similarly, the receiver may weight the transmissions from multiple transmitters.

Abstract: A method for estimating a channel from received signals transmitted via the channel, includes the steps of receiving the received signals with receiving sensors of a receiving device. The received signals are composed of a plurality of subscriber signals. The subscriber signals are marked with transmitter-specific fine structures. A subscriber signal of the plurality of subscriber signals is transmitted by a plurality of wave elements having differing incidence directions at a receiving point. An incidence direction of at least one of the wave elements is obtained in the receiving device. Directionally selective channel impulse responses are determined from the plurality of received signals and the incidence direction of the at least one wave element.

Abstract: Signals in the form of wave elements of one or more subscriber signals are received at a receiving device assigned a number Ka of receiving sensors and the direction of the signals is estimated. Ka received signals are received via the receiving sensors and are composed of at least one subscriber signal which has a transmitter-specific fine structure impressed on it. A kth subscriber signal, with k=1 . . . K, is transmitted by means of Kd wave elements whose directions of arrival at the receiving location differ. Channel impulse responses assigned to the Ka receiving sensors are determined from the received signals, and the direction of arrival of at least one wave element is determined from the channel impulse responses. The direction estimation can advantageously be used in mobile radio, radar, sonar or seismic measurement systems.
