Abstract
In accordance with a detection method in a wireless communication system, an initial hypothesis for a starting position of a desired signal within a received wireless communication signal may be determined. The desired signal may have a conjugate symmetric property. At least one correlation value may be determined based on the initial hypothesis. The at least one correlation value may indicate the extent to which at least one sample sequence selected from the received signal has the conjugate symmetric property.
Claims25
A detection method in a wireless device, comprising:
- determining an initial hypothesis for a starting position of a desired signal within a received signal, wherein the desired signal has a conjugate symmetric property;
- and
- determining at least one correlation value based on the initial hypothesis, wherein the at least one correlation value indicates the extent to which at least one sample sequence selected from the received signal has the conjugate symmetric property and is determined using circular convolution.
A wireless device, comprising:
- a coarse detector that is configured to determine an initial hypothesis for a starting position of a desired signal within a received signal, wherein the desired signal has a conjugate symmetric property;
- and
- a correlator that is configured to determine at least one correlation value based on the initial hypothesis, wherein the at least one correlation value indicates the extent to which at least one sample sequence selected from the received signal has the conjugate symmetric property and is determined using circular convolution.
An apparatus, comprising:
- means for determining an initial hypothesis for a starting position of a desired signal within a received signal, wherein the desired signal has a conjugate symmetric property;
- and
- means for determining at least one correlation value based on the initial hypothesis, wherein the at least one correlation value indicates the extent to which at least one sample sequence selected from the received signal has the conjugate symmetric property and is determined using circular convolution.
A computer-program product for performing detection in a wireless communication device, the computer-program product comprising a non-transitory computer readable medium having instructions thereon, the instructions comprising:
