Copies of the papers presented at, or published for DCC are available in various ways. A paper printed in the proceedings will be available for purchase in most cases in hard copy as the DCC proceedings. It will in most cases also be available as an individual paper in PDF format as a free download via a link below the abstract (where available) It may also be available on CD-ROM. A paper printed in the proceedings may not have been presented at the conference. Also a presentation at DCC may not be in the printed proceedings. In those cases it may be available on DVD, CD-ROM or as a MP3 download. Links to what is available will be on the page specific to the particular year's DCC.

32nd ARRL and TAPR Digital Communications Conference
September 21-23, 2013
(CAB) Controllable Altitude Balloon Proposal
by Pedro Converso LU7ABF
- Abstract: This paper proposes a method for controlling high altitude ballons.
Noise Power Ratio (NPR) Testing of HF Receivers
by Adam Farson VA7OJ/AB4OJ
- Abstract: Noise-power ratio (NPR) testing is a performance test technique in which a notched noise-band is applied to the input of the DUT, and the output of the DUT is connected to a selective level meter whose bandwidth is less than that of the notch in the noise spectrum. The ICN (idle-channel noise) is measured with the noise-band (1) not notched and (2) notched
High Performance BPSK31: Ideas for a New Generation
by John A. Gibbs NN7F
- Abstract: Advancements in Personal Computing capabilities and signal processing theory present an opportunity to improve Amateur Radio.s most popular digital mode, BPSK31. Error reduction methods are investigated and simulations are compared to theory. Areas for further investigation are suggested.
Raspberry Pi Applications in Digital Communications:
A Mobile Xastir-Based APRS Station
by John A. Hansen W2FS
- Abstract: TNC-Pi is a version of the TNC-X KISS mode TNC that is designed specifically to plug into a Raspberry Pi computer. Coupled with a mobile monitor, and keyboard/trackpad, it makes it possible to assemble mobile APRS station for a very low cost. This paper describes the components needed for this and provides step by step instructions on how to configure it.
Gnuradio Companion module for openHPSDR Hermes / Metis SDR Radio
by Tom McDermott N5EG
- Abstract: This paper discusses the design and implementation of software that provides an interface for the OpenHPSDR Hermes/Metis Ethernet-based SDR transceiver module to Gnuradio. General design requirements imposed by Gnuradio and the hardware itself are discussed. Some applications of Gnuradio using this software are illustrated. The module has been tested with Hermes and should be compatible with Metis. The module has been tested on Ubuntu 12.04, 12.10, and 13.04. It has been tested at the time of this writing through the current version of Gnuradio 3.6.5
Evaluating OLSR and B.A.T.M.A.N over D-STAR
by John Ronan EI7IG and Darren Long G0HWW
- Abstract: This work examines the performance of both the Optimized Link State Routing (OLSR) protocol and the Better Approach To Mobile Ad hoc Networking (B.A.T.M.A.N.) protocol over the Digital Smart Technologies for Amateur Radio - Digital Data mode (D-Star DD). A comparison was performed with differing parameters to evaluate what impact, if any, they would have on overall goodput, over and above the default settings. In this scenario, with multiple nodes, the experimental results show that the housekeeping data being transmitted by both protocols can significantly and adversely impact the available bandwidth on the channel.
Narrowband IP over Amateur Radio Networks (NIPARnets)
Next-Generation Networking for Amateur Radio
by Timothy J. Sal, AB0DO
- Abstract: The Narrowband IP over Amateur Radio Networks (NIPARnets) proposed here offer an opportunity to design, develop, and deploy a new generation of amateur radio digital networks. NIPARnets will employ state-of-the-art protocols and technologies: they will leverage and extend recent work by researchers, standards development organizations, and others. These networks will offer amateurs a digital network that will make effective use of our valuable narrowband very high frequency (VHF) and ultra-high frequency (UHF) radio frequency (RF) channels. NIPARnets will connect seamlessly with the Internet, enabling amateur devices to appear to be part of and directly accessible from the Internet. These networks will benefit amateur radio beyond simply providing a new, more capable, more efficient network for use on narrowband channels: they will help attract new members to the amateur radio community, particularly those who want to experiment directly with wireless data networks and the technologies that power the Internet. Equally importantly, NIPARnets will help protect our VHF and UHF spectrum by demonstrating how we can use this scarce resource to help advance the radio and networking arts.

- Abstract: How to build and setup the MDSR Software V2.6, build the LIF2012 Converter and install it into a Transceiver Installation procedures for FT-817, FT-857, FT-897, IC7000, IC-703 as addendum.
A Software Defined Radio for Mesh Networks
by John B. Stephensen KD6OZH
- Abstract: This paper describes an FPGA-based SDR transceiver that may be used for ad-hoc wireless mesh networking on the VHF and UHF amateur bands. The architecture allows simultaneous use of two channels, a fixed frequency control channel and a variable frequency data channel, to overcome bandwidth limitations and prevent inter-node interference. Multiple transceivers may cooperate to form a layer-2 mesh network that looks like an Ethernet switch to users. Internal software implements derivatives of AODV and ODMRP with source multi-point relays for efficient unicast, broadcast and multicast transmission.
