Hf Xl: Adaptive Wideband Hf Transmissions
نویسندگان
چکیده
This paper presents a solution to increase the throughput of an HF (High Frequency) physical (PHY) layer in particular to allow for services such as IP over HF. Additionally, this new PHY layer can improve the adaptability of the waveform to the channel variations, in particular to limit the retransmissions due to errors. Taking into consideration the existing HF spectrum occupancy and its high interference level, the proposed “HF XL” approach relies on narrow band (3 kHz) non-contiguous channels bonding.

Performance of a nonlinear adaptive SBS-MAP detector using soft-statistics for digital transmissions over HF channels
The effectiveness of the recently proposed adaptive Maximum A Posteriori (MAP) receiver in Cusani and Mattila is verified for digital HF links between mobile and/or fixed units. Following Cusani and Mattila, a suitable MAP algorithm is employed to compute Symbol-by-Symbol (SBS) the A Posteriori Probabilities (APP’s) of the channel state; from these, the detected data stream is obtained. The sam...

Harris Corporation has an interest in making HF radios a suitable medium for wireless information networks using standard Internet protocols. Although HF radio links have many unique characteristics, HF wireless subnets can be subject to many of the same traffic flow characteristics and topologies as existing line-of-sight (LOS) radio networks, giving rise to similar issues (media access, conne...

Increasing data throughput of Multipath time-varying HF channel by employing decision feedback equalization is addressed. In this paper, we propose multichannel FQRD-RLS adaptive filtering algorithm employing weight extraction in Decision-directed mode. A comparison between this technique and IQRD-RLS algorithm is performed. Simulation is conducted under channel parameters with respect to MIL-S...
متن کاملEvaluation of HF ALE Linking Protection
The resurgence of interest in high frequency (HF) radio may be largely attributed to the success of automation in making HF usable by operators with minimal HF training. Unfortunately, Automatic Link Establishment (ALE) technology opens automated HF networks to possible hostile manipulation. To counter this vulnerability, a scheme called Linking Protection (LP) has been developed and standardiz...
