Abstract :
The mobile Internet has finally arrived with the sky-rocketing usage increase of HSPA. LTE, WiMAX and evolved WiFi are the upcoming wireless standards which are based on OFDM and MIMO. The mentioned standards have already started the evolution process with LTE-advanced, IEEE 802.16m and IEEE 802.11n. New technology building blocks are on its way like cooperative MIMO, relaying and self-organizing networks. Increase of data-rate is one target, but the energy consumption both on the terminal and network side are important as well. This paper discusses the challenges imposed by developments in the wireless industry. Advanced signal processing can play a major role in addressing these challenges.
