“…To put the 2-way relaying results into perspective, we compare them against the 1-way relaying results from [15] for MSK source signal and phase-forward relay signal. The BER curves shown in these figures were obtained from the semi-analytical expression in (22) and as well as from simulation. The two sets of results are in good agreement.…”

“…Naturally, in the presence of fading and noise, these phase derivatives are subjected to distortions. However, as long as the channel's average signal-to-noise ratio is at a decent level, the decision rule in (22) will still enable us to recover the data reliably. Further discussion on the optimality of (20) can be found in [15].…”

In this article, we propose the idea of phase-superposition-phase-forward (PSPF) relaying for 2-way 3-phase cooperative network involving constant envelope modulation with discriminator detection in a time-selective Rayleigh fading environment. A semi-analytical expression for the bit-error-rate (BER) of this system is derived and the results are verified by simulation. It was found that, compared to one-way relaying, 2-way relaying with PSPF suffers only a moderate loss in energy efficiency (of 1.5 dB). On the other hand, PSPF improves the transmission efficiency by 33%. Furthermore, we believe that the loss in transmission efficiency can be reduced if power is allocated to the different nodes in this cooperative network in an 'optimal' fashion. To further put the performance of the proposed PSPF scheme into perspective, we compare it against a phase-combining phase-forward technique that is based on decode-and-forward (DF) and multi-level CPFSK re-modulation at the relay. It was found that DF has a higher BER than PSPF and requires additional processing at the relay. It can thus be concluded that the proposed PSPF technique is indeed the preferred way to maintain constant envelope signaling throughout the signaling chain in a 2-way 3 phase relaying system.

“…Since the power of the delayed ligna' is considerably weaker than that of the main signal (e.g., os D o,), this assumption is justifiable for the interfering signals which are weaker than the desired signal in any case. 2 2…”

“…Considering the bit timing delay, we distinguish two cases: (1) where the bit timing offset (say) z of an interferer is random and distributed in the interval (0, T) where T is the symbol duration, and (2) where z = 0 . Since Case (1) is the most general and realistic, we analyze it in detail, and for compxison, we also treat Case (2). The power level of an interferer can be accommodated into the analysis by defining a CIR.…”

Performance of GMSK in frequency selective Rayleigh fading and multiple cochannel interferers

The two-ray Rayleigh fading model accounts for the frequency selective fading experienced by the received signals in some digital cellular systems. For such fading channels, binary error probabilities of GNISK with discriminator detection or differential detection are considered in the presence of multiple, Rayleigh-faded, independent, cochannel interferers. The paper drives an exact solution for the average error probability and a near-exact but less computationally intensive solution. The near-exact solution is virtually indistinguishable from the exact solution for large carrier-to-interference ratios (CIR,. To establish the accuracy of the results, numerical examples are given.
