Classification: CPC H | IPC H

Claim 15:
16. A receiver comprising:
a receiver operable to receive a plurality of reference signals; and
a processor operable to:
for a given reference signal of the plurality of reference signals:
determining a noise estimation; and
determine a distance metric and a log-likelihood ratio (LLR) of the noise estimation; and

determine a final LLR based on of the distance metric and the LLR of each noise estimation;

wherein the processor is further operable to:
combine the LLRs of at least two noise estimations; or
select the LLR of a particular noise estimation based on the distance metric of the particular noise estimation;
wherein for a first reference signal of the plurality of reference signal, the noise estimation is a first noise estimation, the distance metric is a first distance metric, and the LLR is a first LLR;
for a second reference signal of the plurality of reference signals, the noise estimation is a second noise estimation, the distance metric is a second distance metric, and the LLR is a second LLR;
wherein the processor is further operable to:
determine a combined noise estimate, wherein determining of the combined noise estimate comprises:
combining the first LLR and the second LLR; or
determining that the second distance metric is nearer to a threshold value than the first distance metric; and determining the combined noise estimate according to the second noise estimation.
