Correction to "Two-Way AF Relaying in the Presence of Co-Channel Interference" [Aug 13 3156-3169]

Two closed-form expressions for the end-to-end cumulative distribution function (CDF) and outage probability of two-way interference-limited amplify-and-forward (AF) relaying were recently presented in Equations (19) and (24) in the above titled paper (ibid., vol. 61, no. 8 pp. 3156-3169, Aug. 2013). However, the expressions contain a notational error. A correction is presented here.
