Chip rate of wcdma
Did you know?
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 … WebChip rate of WCDMA is 3.84 Mchips/sec (ii). WCDMA frame duration is 10msec (iii). Spreading factor is the ratio between chip rate and bit rate.From the given plot, it can be calcul …
WebChip rate: WCDMA uses a 3.84 Mc/s rate in a 5 MHz channel. Wider bandwidth (10 or 15 MHz) are also allowed. Frames: WCDMA standardizes 10 ms frames. These frames are … 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. Objects that exist in the environment cause multiple reflections, refractions, diffractions and attenuations on the signal.
