EDGE Evolution as the latest TDMA based communication standard offers a simple solution to increase the spectral efficiency of GSM mobile communication systems. This standard offers sufficient performance for most mobile applications and the benefit of reusing the existing hardware for mobile operators. This can be interesting for rural areas and developing countries, where large cell areas and low infrastructure costs are demanded by the communication services companies.
Evolved EDGE introduces several new technical features which require new sophisticated solutions, as e.g. transmission modes with higher modulation orders. These exacerbate the channel equalization and demodulation of the received signals.
In this project the digital baseband for Evolved EDGE has been explored with a focus on channel equalization. The most promising algorithms have been used for the realization of a receiver ASIC which supports 4 modulation types and 23 different coding schemes, as required for GSM, GPRS, EDGE and Evolved EDGE. With a measured power consumption of less than 5 mW in all modes, this prototype shows that Evolved EDGE can be realized at preserving the low-power attribute of 2G/GSM devices.
