Capacity Limits of Spectrum-Sharing in Hoyt (Nakagami-q) Fading Channels Romero-Jerez, Juan Manuel López-Martínez, Francisco Javier Electrónica - Tecnología A channel capacity analysis is presented in this work for a spectrum-sharing cognitive radio link in which the fading experienced by the signal is modeled with the Hoyt (Nakagami-q) distribution. Based on a novel formulation of the squared Hoyt distribution derived by the authors, simple expressions for the capacity of the secondary link in a number of scenarios of interest are derived, which are given in terms of easy-to-compute finite-range integrals of elementary functions. The effect of fading severity in the secondary transmitter-primary receiver (ST-PR) and secondary transmitter-secondary receiver (ST-SR) links, and the impact of different antenna gains on the system performance are analyzed. We show that in the presence of severe fading for the ST-PR link, the capacity of the ST-SR link is increased. 2016-10-06T12:11:14Z 2016-10-06T12:11:14Z 2016 2016-10-06 conference output http://hdl.handle.net/10630/12165 http://orcid.org/0000-0001-7844-4574 eng 2016 IEEE 84th Vehicular Technology Conference: VTC2016-Fall Montreal, Canadá 18 Septiembre 2016 open access by-nc-nd
