Classes
class	itpp::LFSR
	Binary Linear Feedback Shift Register (LFSR) The LFSR is on Fibonacci form (see p. 104 in Peterson, Ziemer and Borth, "Introduction to Spread Spctrum communications", Prentice-Hall, 1995) If the connect_polynomial=1+g1*D+g2*D^2+...+gr*D^r is a primitive polynomial, a Maximum Length Sequence (m-sequence) of length N=2^r-1 is constructed. Use an arbitrary state not equal to zero, to get a phase of the m-sequence For a table of primtive polynomials see p. 117 in the reference above or a suitable book on coding. More...
class	itpp::Gold
	Gold Sequences. More...
Functions
smat	itpp::wcdma_spreading_codes (int SF)
	Generates the OVSF (orthogonal variable spreading factor) spreading codes used in WCDMA. The codes are written row-wise in the return matrix.
