Embodiment Construction
[0127] The method of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0128] The method of the invention is applicable to any array antenna mobile communication system adopting MC-CDMA transmission scheme.
[0129] With reference to the array antenna MC-CDMA system uplink receiving structure block diagram of Fig. 1, the concrete steps of a kind of array antenna MC-CDMA system uplink receiving method comprise, to any user (k):
[0130] Step 1, the signal r received by the first array element of the array antenna 1 (t) respectively sent to L carrier signal separation modules (1-1-1), (1-2-1), ..., (1-L-1), to obtain the output signal x k,1,1 (t)=r 1 (t)(cos(ω 1 (t-τ k,l ))+sin(ω 1 (t-τ k,l ))), x k,2,1 (t)=r 1 (t)(cos(ω 2 (t-τ k,2 ))+sin(ω 2 (t-τ k,2 ))), ..., x k,L,1 (t)=r 1 (t)(cos(ω L (t-τ k,L ))+sin(ω L (t-τ k,L ))); At the same time, the signal r received by the second array element 2 (t) respectivel...
