Design of a flexible low-power modem chip for point to point radio link cellular backhaul applications

In the past few years, mobile networks have been offering higher data rates services, with the introduction of GSM-GPRS and the roll-out of 3G systems. As a consequence of this growth, increased flexibility and capacity has been required in the cellular backhaul network The flexible low-power modem chip presented here is a main building block of a new family of channel coding and constellation agile spectrum-efficient radio links. The design has been implemented on 130 nm ASIC technology.
