Trends in Transmitter & Receiver Architectures for Mobile Devices and Basestations by Andrew Bateman, Carole Mayhew, Graham Carter |
|
 |
In order to make the information signal (e.g. data) pass through the air, it must be modulated on to a carrier signal whose frequency is well suited to the propagation environment, conforms to the licensed operating bands, and is sufficiently stable to allow detection by a tuned receiver in the presence of interference.
The method of imposing the information signal onto the carrier signal is termed modulation and must be accomplished cost effectively and accurately for maximum range and minimum interference. The amplifier is a key part of the transceiver, and must be efficient (dc power in to RF power out), low cost, non-polluting, and possibly linear. Output power is dictated by regulation, range requirement, battery life, cost and linearity considerations. more>> |

FPGAs in Next Generation Wireless Networks by Ron Warner, Lattice Semiconductor |
|
 |
Programmability is a characteristic that runs throughout the evolution of basestation design. Designs often were started before a specification had been completely ratified. Basestations were heavy users of ASIC devices and FPGAs were often used as interfaces and more>> |
