Technology Roadmap
To Developing the Universal Radio
• Move the Problem to the Digital Domain
– Today’s GSM Phone uses 100 MIPs
– The GSM channel implemented in the digital domain
requires over 500 MIPs without decimation techniques
– With appropriate pre-filtering, GSM channel filter can be only
5 MIPs… Not Applicable !
• No Talk-Time Degradation
• Battery Capacity Improved Barely 10% in 40 years!
