Detailed Description
Gold Sequences.Constructor & Destructor Documentation
| itpp::Gold::Gold | ( | int | degree | ) |
Class constructor.
Automatic selection of a preferred pair of connections. Just give the degree 
where 
. Only one pair is available for each degree.

Member Function Documentation
| 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.
