METHODS, SYSTEMS, AND MEDIA FOR DETERMINING WHETHER A SIGNAL OF INTEREST IS PRESENT |
| 摘要 |
Methods, systems, and media for determining whether a signal of interest is present are provided, in some embodiments, a system for determining whether a signal of interest is present is provided, the system comprising: at least one hardware processor that is configured to: receive at least one bit value containing information about whether the signal of interest is present from at least one transmitter, wherein the at least one bit value is transmitted from the at least one transmitter at a set of random time instances, and wherein the at least, one bit value is calculated without performing quantization; calculate a combined log-likelihood ratio based at least in part on the at least one bit value; and determine whether the signal of interest is present based at least in part on the combined log-likelihood ratio. |

1. A system for determining whether a signal of interest is present, comprising:
at least one hardware processor that is configured to:
receive at least one bit value containing information about whether the signal of interest is present from at least one transmitter, wherein the at least one bit value is transmitted from the at least one transmitter at a set of random time instances, and wherein the at least one bit value is calculated without performing quantization;calculate a combined log-likelihood ratio based at least in part on the at least one bit value; anddetermine whether the signal of interest is present based at least in part on the combined log-likelihood ratio. |
