Peak LTE data rate can be calculated using the following parameters:<\/p>\n
1 Time-slot=0.5 ms (i.e 1 Sub-frame = 1 ms)
\n1 Time-slot=7 Modulation Symbols (when normal CP length is used)
\n1 Modulation Symbol=6 bits; if 64 QAM is used as modulation scheme<\/p>\n
Data rate for a single carrier=Number of symbols per time slot*Bits per symbol\/Duration of a time slot=7*6\/0.5e-3=84kbps<\/p>\n
If 1200 carriers (100RBs) are used then the aggregated throughput would be=1200*84kbps=100.8Mbps<\/p>\n
If 4×4 MIMO is used then the capacity would increase four fold to=403.2Mbps<\/p>\n
With 3\/4 channel coding the data rate would be reduced to=302.4Mbps<\/p>\n
Note:<\/p>\n
1. A Resource Block (RB)=12 Carriers<\/p>\n
2. Actual data rate would depend upon the instantaneous channel conditions and number of users sharing the resources e.g. going down from 64QAM to QPSK in adverse channel conditions would reduce the data rate from 302.4Mbps to 100.8Mbps. \u00a0Changing the code rate from 3\/4 to 1\/3 would further reduce the data rate to 44.8Mbps.<\/p>\n
