Dear Masters;
How can we calculated Throughput, If Modulation type, SF & No. of codes are given?
If there are any formula, Please explain with an example!!!
Thanks a lot!!!

Lets take HSDPA for example. Spreading factor used is SF16.
We know that WCDMA uses a chip rate of 3.84Mcps.
So prior to spreading the symbol rate is 3.84Mcps/16 = 240Ksps
If we assume a modulation of 16QAM, then each symbol represents 4 bits.
So the bit rate is 4*240Ksps= 960Kbps
Assume that we are using 15 SF16 (the maximum possible for HSDPA) then bit rate is 15*960kbps = 14.4Mbps.
Simple!
