Constructor & Destructor Documentation

itpp::Gold::Gold ( int  degree)

Class constructor.

Automatic selection of a preferred pair of connections. Just give the degree $N = 2^{deg} - 1$ where $deg = \{ 5, 7, 8, 9 \}$. 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.
