Summary

The first complete Evolved EDGE Digital Baseband (DBB) ASIC supporting receive diversity and soft-output Viterbi equalization is presented. It comprises transmitter and receiver with detector and a decoder with an autonomous incremental redundancy implementation. The ASIC reaches a measured sensitivity of -111.8 dBm for single antenna GSM voice channels and achieves the reference interference performance for adjacent channels 12 dB above 3GPP requirements. It occupies 6 mm2 in 130 nm CMOS with a power consumption between 5 and 39 mW.

This chip's successor is stoneEDGE, which also includes an RF transceiver.
