WebThe WCDMA air interface is a direct spread technology. This means that it spreads encoded user data at a relatively low rate over a much wider bandwidth (5 MHz), using a … 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

The basis for the physical layer of WCDMA is spreading of the data to be transmitted to the chip rate corresponding to 3.84 Mchip/s using channelization codes. It is also responsible for coding, transport-channel multiplexing, and modulation of the radio-frequency carrier. truscotts honiton peugeotWebThe chip rate of WCDMA is 3.84 Mcps. Thus, the occupied bandwidth after the RC filter is 1.22 × 3.84 = 4.68 MHz. If oversampled by a factor of 4, the rate is 4.68 × 4 =15.36 Mqcps. 2.2.5 Multipath Propagation.
