[Percutaneous transhepatic cholecysto-lithotripsy].
Authors were the first in Hungary to perform the percutaneous transhepatic cholecystolithotripsy for the removing of gallbladder stones. The method can be performed easily with the necessary skill and it is not too troublesome for the patients. They present their beginning experience.
The design of the LTE physical layer (PHY) is heavily influenced by the requirements for high peak transmission rate (100 Mbps DL/50 Mbps UL), spectral efficiency and multiple channel bandwidths (1.25–20 MHz). Unfortunately, the existing WCDMA turbo interleaver does not permit an efficient high throughput implementation. That is why the 3rd Generation Partnership Project (3GPP) has proposed the quadratic polynomial permutation (QPP) interleaver to rectify this situation. In this paper, we will study the performances of QPP interleaver for LTE encoder channel for different configurations of LTE system and we study the effect of LTE channel turbo encoder for the transmission over a wireless multipath channel.
