We consider a single-input single-output block-fading channel with B fading blocks, whose system model is given by the following, y b = √ SNRh b x b +z b b = 1, . . . , B (1) where h b ∈ C is the b-th fading coefficient, y b ∈ C L is the received signal vect...
This work considers the achievable diversity for coded systems appropriately characterized by a block-fading channel model. We are primarily interested in cases where the number of uncorrelated fading channel realizations (blocks) F, is small, so that ideal interleaving assumptions do not hold. This ...
This work considers the achievable performance for coded systems adapted to a multipath block-fading channel model. This is a particularly useful model for analyzing mobile-radio systems which employ techniques such as slow frequency-hopping under stringent time-delay or bandwidth constraints for slowly...
channel model. In this thesis, we derive a union bound on the performance of binary coded systems over block fading channels. Noncoherent and coherent receivers are considered with different assumptions on the channel side infor- mation (SI) at the receiver. We derive the union bound for Raylei...
We consider the trade-off between multiplexing gain and diversity gain for the block-fading sub-channel model. The channel vector may be rank deficient and has arbitrary covariance structure. We derive this trade-off by considering the scaling law of the ergodic capacity, which represents the mult...

In a block-fading channel model the codeword is composed of multiple blocks, the fading coefficients are constant over one fading block, but are independent over block to block. It has been shown in [10] that for block-fading channel, if we code across L quasi-static fading intervals ...

experience independent quasi-static fading levels, hence the block fading channel model is appropriate for this system. From Figures 1 and 2, we can observe that our analytical PEP matches the simulated PEP exactly. −12 −10 −8 −6 −4 −2 0 2 4 6 8 ...
Information-guided channel-hopping technique employing multiple transmit antennas was previously proposed for supporting high data rate transmission over fading channels. This scheme achieves higher data rates than some mature schemes, such as the well-known cyclic transmit antenna selection and space-time...
