Claim of US Patent No. 9,131,507

1. A method for receiving signals, comprising:
receiving signals on at least one receiving branch, which includes at least two reception units, including at least one data
reception unit and at least one pilot reception unit, and said signal is a codeword in a transmission codebook;

calculating a metric value for each codeword in said transmission codebook according to said received signal and obtaining
the maximal metric value;

determining the codeword corresponding to said maximal metric value as the demodulation output if said maximal metric value
is larger than a threshold value; and

determining discontinuous-transmission DTX as the demodulation output if said maximal metric value is smaller than a threshold
value;

wherein, calculating the metric value for each codeword in said transmission codebook comprises:
processing the received signal on all reception units of each said receiving branch and a codeword to obtain a temporary metric
value corresponding to said receiving branch and said codeword; and

summing the temporary metric values corresponding to all said receiving branches and said codeword to obtain the metric value
for said codeword.
