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 … 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. …
