Abstract
A system and method for signaling and detecting in wireless communications systems are provided. A method for processing information includes operating in a first phase, operating in a second phase, and processing the detected information. The first phase includes iteratively inverting a first filtering operation on received signals, and the second phase includes iteratively inverting a second filtering operation on received signals with consideration given to a first estimation error of symbols of the first user and a second estimation error of symbols of the second user.
Claims28
A method for processing information, the method comprising:
- operating in a first phase, wherein the first phase comprises iteratively inverting a first filtering operation on received signals;
- operating in a second phase, wherein the second phase comprises iteratively inverting a second filtering operation on received signals with consideration given to a first estimation error of symbols of a first user and a second estimation error of symbols of a second user;
- and
- processing the detected information using a processing unit.
A method for processing received information, the method comprising:
- receiving a signal;
- performing basic mode detection on the signal, thereby producing a partially detected signal;
- performing composite mode detection on the partially detected signal, thereby producing a detected signal;
- and
- decoding the detected signal.
A receiver comprising:
- an iterative demodulator, the iterative demodulator configured to be coupled to a plurality of signal inputs and to detect information in received signals based on soft estimates of the information;
- and
- a further processing unit coupled to the iterative demodulator, the further processing unit configured to provide further processing of soft estimates of the information based on transmit power levels of the information.
A communications device comprising:
- a transmitter configured to transmit signals;
- and
- a receiver coupled to the transmitter, the receiver configured to receive signals and to detect information in the received signals based on soft symbol estimates of the information in the received signals.
