Chip rate of wcdma

WebThe 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.

WebWCDMA is based on 5-MHz channels using direct-sequence spread spectrum with a chip rate of 4.096 Mcps operating with paired uplink/downlink channels in an FDD mode. (Recently, the chip rate has been reduced to 3.84 Mcps, but the system characteristics remain the same.) WebWCDMA uses Direct Sequence spreading, where spreading process is done by directly combining the baseband information to high chip rate binary code. The Spreading Factor is the ratio of the chips (UMTS = … WebJan 7, 2006 · 279. wcdma band width. Resolution depends on the chip rate. In WCDMA the chip rate is Rc=3.84 Mcps. hence, the chip duration is 1/Rc=0.26 usec. Hence, the receiver can resolve (i.e, distinguish) any two paths with relative delay > 0.26 usec. This is done using the code matched filter. The bandwidth depends on the pulse shaping filter … iphone se a2296 何世代
