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...
A simple model is the block fading 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 information (SI) at the receiver. We...
We consider a multi-input multi-output (MIMO) block-fading channel with a general model for channel state information at the transmitter (CSIT). The model covers systems with causal CSIT, where only CSIT of past fading blocks is available, and predictive CSIT, where CSIT of some future ...

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...
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...
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...
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 ...
2.2 Channel model Consider the downlink of a block fading cellular system with a single BS andNreceivers. While we briefly discuss random request networks, we mainly focus on fixed multiuser setups, where all users are always active, that is,Nis a fixed finite number. In each time slot, a...
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 ...
