Iterative decoding with intentional SNR/SIR reduction |
October 27, 2009 |
| The excess signal-to-interference ratio (SIR) or the like of a communication channel is determined by repeatedly decoding received information with successively reduced effective SIR. The step size in an outer power control algorithm, for example a Jump Algorithm, such as that common |

Determination of a channel estimate of a transmission channel |
July 14, 2009 |
| A method of determining a channel estimate of a first transmission channel in a communications system. The method comprises deriving a first set of channel estimates from symbols received through said first transmission channel; deriving a second set of channel estimates from symbols rec |

Interference estimation in the presence of frequency errors |
June 30, 2009 |
| Methods and apparatus for estimating interference level in a receiver are dominated by the receiver's residual frequency error when the interference is low. The interference estimation method can be changed when the interference is low such that it compensates for the effects of resi |

Adaptive threshold for HS-SCCH part 1 decoding |
July 29, 2008 |
| Whether to abort reception of a multi-part message in a code division multiple access communication system is determined by receiving a part of the multi-part message. Correlating the received part of the multi-part message with a known sequence generates a correlation value. The cor |
