Study of a Modified Polar Sigma-Delta Transmitter Architecture for Multi-Radio Applications

Original language description

Polar Sigma Delta architecture has been previously proposed as an universal architecture able to offer multi-radio transmission for mobile systems. This paper briefly describes polar sigma delta transmitter architecture and proposes two modifications toit, first to use the phase signal as control signal for the Phase Locked Loop (PLL) based frequency synthesizer and second to perform a digital mixing instead of analog mixing when recombining envelope and phase signals. Simulations of the modified architectures have been carried out for mobile WiMax (Worldwide Interoperability for Microwave Access) standard based technology, a very exigent communication standard in terms of envelope magnitude range and channel bandwidth. Results are presented and new architectures advantages and drawbacks are pointed out.
