It provides a leap in performance and a complete move to packet-based processing ... Figure 1 illustrates the structure of an example LTE subframe. The subframe comprises a number of OFDM symbols.

Virtually all major new wireless technologies, including WiMAX and LTE, are based on orthogonal frequency-division multiplexing (OFDM), which has emerged as the wireless spectral efficiency leader.

It provides a leap in performance and a complete move to packet-based processing. In the physical (PHY) level of the LTE specification, specific challenges exist when dealing with higher data ...
