Iterative Channel Estimation for EGPRS
01 January 2000
The Enhanced Data GSM Evolution (EDGE) standard will increase the data rates in a GSM system significantly. An 8-PSK modulation scheme is proposed which is more sensitive to impairments in the transmission medium than GMSK modulation in the GSM system. Channel estimation plays a crucial part on the receiving end to overcome those impairments. In this extended abstract, we investigate different iterative channel estimation (ICE) techniques. In order to reduce complexity sub-optimum algorithms are addressed. Comparisons with the GSM system show that not all algorithms are suitable for the EDGE system. Simulation results show that with ICE the BLER in EGPRS can be improved by almost 2 dB.
