This scrambling is removed at the receiver after demodulation. When the LFSR runs at the same bit rate as the transmitted symbol stream, this technique is referred to as scrambling. When the LFSR runs considerably faster than the symbol stream, the LFSR-generated bit sequence is called chipping code. See more In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. The most commonly used linear function of single bits is See more Named after the French mathematician Évariste Galois, an LFSR in Galois configuration, which is also known as modular, internal XORs, or one-to-many LFSR, is an alternate … See more Binary LFSRs of both Fibonacci and Galois configurations can be expressed as linear functions using matrices in See more • Ones and zeroes occur in "runs".

http://m.chinaaet.com/article/34905 WebBut since Gold Code does, in fact, combine two m-sequences to generate the Gold sequence and each m-sequence can be easily implemented (in hardware) with a linear feedback shift register (LFSR), like the two on your Gold Code page. And the way we describe which individual bits are used in the feedback logic of the LFSR is by generator polynomials.
