• Pseudorandom number sequence — A Pseudorandom number sequence is a sequence of numbers that has been computed by some defined arithmetic process but is effectively a random number sequence for the purpose for which it is required. Although a pseudorandom number sequence in… …   Wikipedia

• Pseudorandom binary sequence — A binary sequence (BS) is a sequence of N bits, :a j for j=0,1,...,N 1, i.e. m ones and N m zeros. A BS is pseudo random (PRBS) if its autocorrelation function :C(v)=sum {j=0}^{N 1} a ja {j+v}has only two values::C(v)=egin{cases}m, mbox{ if }… …   Wikipedia
