Did you know?
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 of +1 or −1 amplitude, which is multiplied by a data sequence (similarly +1 or −1 representing the message WebCscramb= c1(w0+ jc2’w1) where w0and w1are chip rate sequences defined as repetitions of: w0= {1 1} w1= {1 -1} Also, c1is a real chip rate code, and c2’ is a decimated version …
