Abstract:
Systems and methods for generating spectrally shaped pseudo random noise sequences are described, which may include generating an L-level PN sequence, where L is an integer greater than 1; up-sampling the PN sequence by a factor of M, where M is an integer greater than 1; and filtering the up-sampled PN sequence using a finite impulse response (FIR) filter of length M, where the coefficients of the FIR filter are chosen from a set of pre-determined values.
