Patent ID: 8189715

Claim:
A receiver for receiving data symbols having a symbol period with duration SP, wherein SP is the symbol period duration, comprising: N input terminals for retrieving N antenna signals, wherein in N≧2; a multiplexer having N inputs coupled to the N input terminals respectively, for selecting the N antenna signals one by one under control of a control signal so as to obtain a combined antenna signal; a processing unit for performing an autocorrelation function on the combined antenna signal so as to obtain a combined signal; a demultiplexer for splitting in dependence of the control signal the combined signal into N signals corresponding to the N antenna signals; N first integrator units for integrating the N signals so as to obtain N integration signals; a control signal generator for generating the control signal wherein the control signal generator is arranged to generate in a first mode a control signal which enables the multiplexer to select equally in time over a symbol period the N antenna signals and wherein at least one of the N antenna signals is selected more than one time in a symbol period, and wherein the control signal generator is arranged to generate in a second mode in dependence of the N integration signals a control signal which enables the multiplexer to select only one of the N antenna signals.
