Abstract
In an RF communication system, aspects for processing multipath clusters may comprise tracking a plurality of received clusters of signals and estimating a phase and amplitude of at least a portion of each of the plurality of received clusters of signals. Each of the plurality of received clusters of signals may be specified in time and an aggregate of received signal paths in a single cluster for a single base station may be processed. At least one cluster path processor may be assigned to process the plurality of received clusters of signals from each transmitting antenna at a single base station. At least one cluster path processor may be assigned to each of a plurality of base stations that are utilized for soft handoff.
Claims20
A receiver for processing a received signal, the received signal including a first signal that is received over a first signal path and a second signal that is received over a second signal path, comprising:
- first cluster path processor and a second cluster path processor configured to estimate the first signal path to provide an estimated first signal path and the second signal path to provide an estimated second signal path, respectively;
- a first maximum ratio combining module and a second maximum ratio combining module configured to convolve the estimated first signal path with the received signal to provide a first weighted signal and the estimated second signal path with the received signal to provide a second weighted signal, respectively;
- a first despreader and a second despreader configured to apply a first code to the first weighted signal to provide a first set of symbols and a second code to the second weighted signal to provide a second set of symbols, respectively;
- and
- a macro combiner configured to combine the first set of symbols and the second set of symbols to provide a recovered set of symbols.
A method for processing a received signal, the received signal including a first signal that is received over a first signal path and a second signal that is received over a second signal path, comprising:
- estimating, by a communication receiver, the first signal path to provide an estimated first signal path and the second signal path to provide an estimated second signal path;
- convolving, by the communication receiver, the estimated first signal path with the received signal to provide a first weighted signal and the estimated second signal path with the received signal to provide a second weighted signal;
- applying, by the communication receiver, a first code to the first weighted signal to provide a first set of symbols and a second code to the second weighted signal to provide a second set of symbols;
- and
- combining, by the communication receiver, the first set of symbols and the second set of symbols to provide a recovered set of symbols.
A receiver for processing a received signal, the received signal including a signal that is received over a signal path, comprising:
- a cluster path processor configured to estimate the signal path to provide an estimated signal path and a timing signal indicating a timing index of the received signal as received over the signal path;
- a maximum ratio combining module configured to convolve the estimated signal path with the received signal in accordance with the timing signal to provide a weighted signal;
- and
- a despreader configured to apply a code to the weighted signal in accordance with the timing signal to provide a first set of symbols.
