PRMA Performance Evaluation Based on Speech Clipping - Barceló, Martín (1996) (Correct)
....to use in simulations, because the slot duration of the simulated system will not always be exactly 5 ms. and the model doesn t include the hangover effect present in the activity IEEE Int. Conf. on Communications Systems, pp. 1206 1210, Singapore, Nov. 1996 detector of the mobile station. In [9] an extension of the ITU T voice model is presented, based on a real time axis, and including the hangover effect. As the time base is real, it can easily be adapted to any slot duration. This voice model is basically the same Markov process used in [1, 2] and illustrated in Figure 1, but with ....

....will be used as the physical channel for the same talkspurt. This so called in slot signalling makes the protocol very simple and attractive, while keeping a very good performance level. Several papers on the performance evaluation of the PRMA protocol can be found in the technical literature [1, 2, 3, 4, 5]. Most of the existing performance evaluations are basically improvements and variations on [6] these variations include noise, capture effect, distortion, channels with errors or fading and other factors which are closer to the real system but add extra complexity to the original model. However, ....
....to be equal to the EP solutions. All these assumptions make the EPA to be an approximation technique whose results and correct application to a specific system must be validated by other means basically simulation. The EPA gives a poor accuracy when the number of slots per frame is not high [1]. The accuracy is also poor when the number of terminals connected to the system is forced to be high with respect to the number of slots available in the frame even when the number of slots is not low. In Fig. 1 the number of terminals in the contention state c vs. the number of terminals M is ....
