N-sequence
In
telecommunication, an
n-sequence is a pseudorandom
binary sequence of
n< bits that
- (a) is the output of a linear shift register, and
- (b) has the property that, if the shift register is set to any nonzero state and then cycled, a pseudorandom binary sequence of a maximum of n = 2m -1 bits will be generated, where m is the number of stages, i.e. , the number of bit positions in the register, before the shift register returns to its original state and the n-bit output sequence repeats.
Note: The register may be used to control the sequence of frequencies for a
frequency-hopping spread spectrum transmission system or modulate the carrier in a
direct-sequence spread spectrum system.
