Abstract
A method and apparatus for signal combining within a communication system is provided herein. The output of RAKE fingers is combined via a chip combiner. The combined chip stream can be despread with the appropriate Walsh code (defining a particular channel). The resulting symbol stream can then be deinterleaved and decoded.
Claims14
A method for signal combining within a communication system, the method comprising the steps of:
- receiving a first signal at a first finger of a receiver,
- receiving a second signal at a second finger of the receiver;
- generating a first chip stream from the fist signal;
- generating a second chip stream from the second signal;
- combining the first and the second chip streams to produce a combined chip stream;
- and
- Walsh despreading the combined chip stream to produce a symbol stream.
4 more elements
A method for signal combining, the method comprising the steps of:
- receiving a first chip stream, wherein the first chip stream has been despread with a Pseudo Noise (PN) code;
- receiving a second chip steam, wherein the second chip stream has been despread with the PN code;
- combing the first and the second chip streams to produce a combined chip stream;
- and
- Walsh despreading the combined chip stream to produce a symbol stream.
2 more elements
A receiver comprising:
- a first finger path having a first signal as an input and outputting a first chip stream;
- a second finger path having a second signal as an input and outputting a second chip stream;
- a chip combiner having the first and the second chip steam as an input and outputting a combined chip stream;
- and
- a Walsh despreader having the combined chip, stream as an input and outputting a symbol stream.
