In digital communications, a chip is a pulse of a direct-sequence spread spectrum (DSSS) code, such as a pseudo-random noise (PN) code sequence used in direct-sequence code-division multiple access (CDMA) channel access techniques. In a binary direct-sequence system, each chip is typically a rectangular pulse … See more Orthogonal variable spreading factor (OVSF) is an implementation of code-division multiple access (CDMA) where before each signal is transmitted, the signal is spread over a wide spectrum range through the use of … See more • Baud • GPS signal structure See more • CDMA basics See more WebApr 9, 2024 · The transmit signal is a spread-spectrum signal containing the bit information, with the spreading spectrum code length of N = 63, the chip width T c = 4 ms, and the carrier frequency of 1000 Hz. The sampling frequency is set to 16 kHz.
Webto be spread are represented by real -valued sequences, i.e. the binary value "0" is map ped to the real value +1, while the binary value "1" is mapped to the real value –1.

WebA pseudo-noise code ( PN code) or pseudo-random-noise code ( PRN code) is one that has a spectrum similar to a random sequence of bits but is deterministically generated. The most commonly used sequences in direct-sequence spread spectrum systems are maximal length sequences, Gold codes, Kasami codes, and Barker codes.
