What is evolved packet system? sagitraz 03-January-2010 04:01:33 AMComments Refer Wiki http://en.wikipedia.org/wiki/3GPP_Long_Term_Evolution Release 8's air interface, E-UTRA (Evolved UTRAN, the E- prefix being common to the evolved equivalents of older UMTS components) would be used by UMTS operators deploying their own wireless networks. It's important to note that Release 8 is intended not just for use over E-UTRA, but is also intended for use over any other IP network, including WiMAX and WiFi, and even wired networks.[11] The proposed E-UTRAN system uses OFDMA for the downlink (tower to handset) and Single Carrier FDMA (SC-FDMA) for the uplink and employs MIMO with up to four antennas per station. The channel coding scheme for transport blocks is turbo coding and a contention-free quadratic permutation polynomial (QPP) turbo code internal interleaver Posted by tmtestid1 |
