Based on the memoryless\nproperty of the service provided by the channel in each block, we formulate the\ntransmission process as a discrete time discrete state $D/G/1$ queueing\nproblem. The obtained results provide a full characterization of block Rayleigh\nfading channels and can be ...

(MIMO) Rayleigh fading channel. The proposed codes use single- input single-output (SISO) component codes based on algebraic number theory in the so called diagonal BLAST (D-BLAST) architecture. Based on a pairwise error probability analysis, we show that the diversity order of the frame ...
Summary: We consider the problem of designing signal constellations for the multiple transmit-multiple receive antenna Rayleigh-fading communication channel, when neither the transmitter nor the receiver know the fading. In particular, by employing the asymptotic union bound (AUB) on the probability of...

frequency-division multiplexing (OFDM) systems with decoupled information-bearing symbols from pilot symbols transmitted over wireless frequency-selective Rayleigh-fading channels, we show that equispaced and equipowered pilot symbols are optimal in terms of minimizing the mean-square channel estimation error...
In this paper, the calculation of the probabilityP_{f}(M, N)of more thanMbit errors in a block ofNbits transmitted over a Rayleigh fading channel using noncoherent frequency shift keying is considered. Accurate approximations toP_{f}(M, N)are derived under the assumption of very slow fading...

We study the use of turbo-coded modulation for wireless communication systems with multiple transmit and receive antennas over block Rayleigh fading channels. We describe an effective way of applying turbo-coded modulation as an alternative to the current space-time codes with appropriate interleaving....
