The architecture of a Software Defined Radio (SDR) multi-standard baseband processor are presented. As the first representative of a new SDR baseband family, the X-GOLD™ SDR20 has been successfully designed and fabricated in a 65nm CMOS process. The physical layer signal processing for GSM, EDGE, GPRS, UMTS, HSPA, GMR1-3G, and LTE can be implemented in software on this single-chip device. Respective GSM, UMTS and LTE lab demonstrations have proven the competitiveness of this SDR approach.
