What is chip sequence in CDMA?

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.

What is chipping sequence?

By combining chromatin immunoprecipitation (ChIP) assays with sequencing, ChIP sequencing (ChIP-Seq) is a powerful method for identifying genome-wide DNA binding sites for transcription factors and other proteins. Following ChIP protocols, DNA-bound protein is immunoprecipitated using a specific antibody.

What is the chip rate in CDMA 2000?

In CDMA2000, the chip rate is 1.2288 Mcps, and the input data rate to the CDMA modulator is 19.2 kbps per Walsh code.

How is the code generated in CDMA?

In Direct-Sequence CDMA, the user signal is multiplied by a pseudo-noise code sequence of high bandwidth. This code sequence is also called the chip sequence. The resulting coded signal is transmitted over the radio channel. Figure: User signal and code are multiplied to generate the coded transmit signal.
