Synchronization & BCH for TDD Frame in LTE Synchronization: Purpose: Achieves alignment between the base station (eNodeB) and User Equipment (UE) in LTE Time-Division Duplex (TDD) frames. Methods: Time synchronization ensures proper timing, and frequency synchronization aligns the carrier frequency. Importance: Synchronization is critical for avoiding interference and optimizing signal reception. Broadcast Channel (BCH): Function: … Read more
What is effect of Antenna Beamwidth in LTE The antenna beam width is measured in degrees between half power points ( -3 DB) compared to the main axis of the petals of the antenna. -3 DB point of reference power (DBM) or voltage (dBv). Beamwidth is expressed in terms of a horizontal (Azimuth) and vertical … Read more
The TX diversity methods in the open-loop mode are as below Space time-block coding-based transmit-antenna diversity (STTD) Time-switched transmit diversity (TSTD). In UMTS STTD the data to be transmitted is divided between two UMTS transmission antennas at the base station site and transmitted simultaneously. The UMTS channel-coded data is processed in blocks of four bits. … Read more
