WebMar 17, 2005 · WCDMA Design Handbook. Developed out of a successful professional engineering course, this practical handbook was originally published in 2005, and provides a comprehensive explanation of the Wideband CDMA (Code Division Multiple Access) air interface of 3rd generation UMTS cellular systems. The book addresses all aspects of … 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 ryan bose apache
