How Cross domain signal analysis in LTE

How Cross domain signal analysis in LTE Regarding cross domain analysis, we see that, I traditionally signal from a receiver RF section can be demodulated and Q components using analog techniques. Today, however, the down conversion signal is digitized by an ADC IF, and usually then fed into the section of the baseband demodulation and … Read more

What is VSWR (Voltage Standing Wave Ratio) and How tilting antenna

What is VSWR (Voltage Standing Wave Ratio) and How tilting antenna VSWR means voltage standing wave ratio which everyone knows but why it comes to calculate in Telecom? When BTS transmit any signal (LTE, CDMA, GSM, WCDMA anyone) then in radio wave transmit through cable and reach to antenna so what? Now I give you … Read more

UL and DL cell based scheduler

The scheduling is performed on cell basis. The two main functions are to decide which UE(s) shall be scheduled, the number of resources and the MCS to be  applied. Furthermore the scheduler needs to be QoS aware. There is priority given to random access responses, control data, HARQ retransmissions. The channel quality may be taken … Read more
