Patent ID: 8855245

Claim:
A method for receiving signals based on dual sensing from one or more sensor nodes at a fusion center in a wireless communication system, the method comprising: allocating Gaussian codes corresponding respectively to the one or more sensor nodes; receiving a signal expressed as below Equation A by multiplication of the Gaussian codes and a transmission signal from at least one sensor node that has been determined to operate among the one or more sensor nodes; recovering a vector signal x on to be recovered using a first measurement matrix (Φ G ) and below Equation B; and recovering a final detection signal x based on a result of the recovering the vector signal x on , wherein the first measurement matrix (Φ G ) is expressed as below Equation C: z=Φ G x on , [Equation A] where z is received signals at a fusion center, x on i = { x i , i ∈ S active 0 , i ∉ S active [ Equation ⁢ ⁢ B ] where S active denotes a set of the at least one sensor node that has determined to operate, and Φ G =[φ G 1 ,φ G 2 , . . . ,φ G N ], [Equation C] where φ G N denotes the Gaussian codes of Nth sensor node among the one or more sensor nodes.
