Work of Synchronization Channels P-SCH & SSCH in 3G WCDMA Synchronization Channel mainly Used for cell search its having Two sub channels: P-SCH and S-SCH, SCH is transmitted at the first 256 chips of every time slot. Primary synchronization code is transmitted repeatedly in each time slot. Secondary synchronization code specifies the scrambling code groups … Read more
In This article you found Application of Tx diversity modes on UMTS downlink physical channel or in other word transmit diversity mode in UMTS. Transmitter-antenna diversity can be used to generate multi-path diversity in places where it would not otherwise exist. Multi-path diversity is a useful phenomenon, especially if it can be controlled. It can … Read more
The table shows representative Link Downlink budget for 3G. Fluctuations in the signal can be represented by a scale and small effects such models are typically used for external circulation. Indoor shadowing results in a large-scale signal change, which may be represented by a log-normal distribution in a manner similar to 3G macro propagation model … Read more
