Constructor & Destructor Documentation

itpp::Gold::Gold int  degree  ) 
 

Class constructor.

Automatic selection of preferred pair of connections. Just give the degree (N=2^degree-1). degree=5,7,8,9 available. Only one pair is available for each degree.

bvec itpp::Gold::shift int  no_shifts  ) 
 

Shift no_shifts steps and output bvec.

int itpp::Gold::get_sequence_length void   )  [inline]
 

Returns the length (period) of a Gold-sequence.

Definition at line 127 of file sequence.h.

bmat itpp::Gold::get_family void   ) 
 

Returns the code family.

The Gold code family is defined by the two m-sequences (mseq1 and mseq2 ) and the sum of mseq1 and all time shifts of mseq2. The return matric thus contain N + 2 rows and N columns, where N is the length of the m-sequences.
