Reduced Precision Redundancy for Satellite Telecommand Receiver Module on FPGA
A novel and highly efficient design of a Software defined radiation tolerant baseband module for a LEO satellite telecommand receiver using FPGA is presented. FPGAs in space are subject to Single Event Upsets (SEUs) due to high radiation environment. Traditionally, Triple Modular Redundancy (TMR) is used for mitigating Single Event Upsets (SEUs). The drawback of using TMR is that it consumes a ...
متن کاملA CDMA Satellite ISDN Modem ASIC
| Code Division Multiple Access (CDMA) promises to become an enabling technology for the future generation of satellite communication services. Spread-spectrum modems for satellite communication currently on the market are targeted towards voice and facsimile communications at rates up to 10 kb/s using transmission band-widths up to 5 MHz. However, emerging multi-media services such as videocon...
متن کاملDSP-Based Satellite CDMA Modem: A Low Complexity Implementation
This paper presents a reliable and low complexity scheme for acquisition, tracking and frequency offset recovery for a DSP-based satellite CDMA modem. An analysis of the performance, in terms of false alarm probability, detection probability and mean acquisition time, is carried out as a function of the complexity and the level of interference. The proposed scheme, based on a dedicated frame fo...
متن کاملA Modem Link Strategy for Optimization of LEO Satellite Throughput
This paper presents a means for optimizing the data throughput for low earth orbit (LEO) satellites by implementing a mission specific error control strategy. Due to limited connectivity and very limited overflight time exposure offered by LEO satellites, it is imperative to volumetrically optimize the data throughput. With power limitations on the space segment and remote groundstations, hardw...
متن کاملDVB-S2 modem algorithms design and performance over typical satellite channels
In this paper we propose a design of the main modulation and demodulation units of a modem compliant with the new DVB-S2 standard (Int. J. Satellite Commun. 2004; 22:249–268). A typical satellite channel model consistent with the targeted applications of the aforementioned standard is assumed. In particular, non-linear pre-compensation as well as synchronization techniques are described in deta...
