Why is Logical root sequence number in Root Zadoff-Chu needed?
Started by 4 years ago●7 replies●latest reply 4 years ago●1150 viewsHi,I have been investigating RACH preamble planning and the properties of Root Zadoff-Chu sequences as used in 3GPP #LTE .From Wikipedia, Zadoff-Chu sequences have...
We know that in #LTE downlink transmit uses #OFDM but in case of uplink transmit, OFDM scheme is not used. Can someone explain the reason behind this?
I would like to know importance of sampling frequency in the baseband. I am using #LTE as an example.If we take a 20 MHz system, the sampling frequency is specified...
Hi,I am interested to know what source coding method is used in case of #WiFi or #LTE. I assume Turbo coding or LDPC are used for channel coding.Thanks,
Hello All,The concept of TTI in #LTE has always confused me. I am giving a brief understanding from a base station perspective.So, assuming BW is fixed (e.g. 20...
Hello All,In case of #LTE, it is mentioned (http://www.sharetechnote.com/html/Handbook_LTE_Dow...) that control channels are made strong wrt to other channels. This...
I am interested to conceptually understand the layer mapping stage in #LTE downlink processing.While all the literature clearly describe how the layer mapping is...
Hello All,I would like to get some clarification wrt to the #LTE downlink process at the Basestation side.I am using a 20 MHz system to be specific in my questions.It...
Pass band in digital up conversion of LTE signals
Started by 7 years ago●6 replies●latest reply 7 years ago●506 viewsHi,I am new to filters and DUC (digital up conversion). I was reading an article from xilinx regarding DUC.It was using a passband of 9.015 MHz in its first stage...
