ITC/USA 2014 Conference Proceedings / The Fiftieth Annual International Telemetering Conference and Technical Exhibition / October 20-23, 2014 / Town and Country Resort & Convention Center, San Diego, CA / This paper describes a system framework for a multi-band, multi-mode software defined radio (MBMM SDR) being developed for next-generation telemetry applications. The system framework consists of the multi-band front-end (MBFE), the multi-mode digital radio (MMDR), and the configuration and control (C2) sub-systems. The MBFE consists of an L/S/C-band transceiver architecture that provides wideband operation, band selection, and channel tuning. The MMDR consists of the software and firmware components for high-speed digital signal processing for the telemetry waveforms. Finally, the C2 consists of the software and hardware components for system configuration, control and status. The MBFE is implemented as a standalone hardware sub-system, while the MMDR and C2 are integrated into a single hardware subsystem that utilizes state-of-the-art system-on-chip (SoC) technology. Design methodologies, hardware architectures, and system tradeoffs are highlighted to meet next-generation telemetry requirements for improved spectrum efficiency and utilizations.

ITC/USA 2012 Conference Proceedings / The Forty-Eighth Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2012 / Town and Country Resort & Convention Center, San Diego, California / The Serial Streaming Telemetry infrastructure is being augmented with the Telemetry Network System, which is a net-centric infrastructure requiring bi-directional communications between the test article segment and the ground station segment. As a result, future radio segments must implement transceiver architecture to support bi-directional communications. This paper presents a design methodology for a multi-band transceiver design. The design methodology is based upon the Weaver architecture to provide coarse selection between the telemetry bands. Utilization of the Weaver architecture allowed for the optimization of multiple transmitter and receiver channels into single channels to support the L/S/C-Band frequency allocations. System-level simulation is presented to evaluate the feasibility of the transceiver design for a multi-band, multi-mode software-defined radio (SDR) platform in support of Telemetry Network System.
