Title: | Impact of CSI latency on HF multi-carrier communications for delay-sensitive applications | Authors: | López-Pérez, J. Pérez-Álvarez, I. A. Zazo-Bello, S. Melián-Gutiérrez, L. B. Amaro-García, A. |
UNESCO Clasification: | 3307 Tecnología electrónica | Issue Date: | 2009 | Journal: | IET Conference Publications | Conference: | IET 11th International Conference on Ionospheric Radio Systems and Techniques, IRST 2009 | Abstract: | Multi-carrier modulations are widely used in HF communications, and particularly OFDM. Delay-sensitive applications can make use of spreading schemes such as OFDM-CDM in order to cope with deep nulls in the channel. If CSI is known at transmitter, it is possible to improve performance using a bit-loading algorithm for OFDM and channel matrix SVD decomposition for OFDM-CDM. If a source of non-ideality in CSI due to latency is taken into consideration, it is shown how performance decreases. A receiver-side technique is applied to OFDM-CDM communications to compensate for delay-incurred matrices mismatch. | URI: | http://hdl.handle.net/10553/42970 | ISBN: | 9781849191234 | DOI: | 10.1049/cp.2009.0068 | Source: | IET Conference Publications,v. 2009, p. 225-229 |
