Cross Layer Analysis of Queuing with AMC Through GMSK Modulation Over Wireless Links

Wireless communication plays an important role in today´s environment. To have an effective communication there must be interaction between different layers of OSI model. In this paper we propose a cross layer design for combining queuing and adaptive modulation and coding (AMC) which includes a new modulation technique Gaussian minimum shift keying (GMSK). Gaussian minimum shift keying (GMSK) modulation is widely used in cellular and PCS applications. One of the important considerations in the use of modulation is the average power spectral density and especially the spectral density characteristics on the tails. Already proposed AMC module for cross-layer design has included the modulations like BPSK, QPSK, QAM etc. In order to maximize spectral efficiency under prescribed delay and performance constraints, GMSK is proposed in this paper.
