Bit error probabilities in a two-rate communication system
نویسندگان
چکیده
We examine a two–rate communication system where the transmission is suspended if the received SNR falls below a given threshold. We assume an FDD system and derive novel closed–form bit error probabilities in the presence of feedback errors in flat Rayleigh fading environment for single antenna transmission, orthogonal space–time block coding and transmit antenna selection. A single–user two–rate system would result in an infrequent use of the channel and long delays, but combined with a physical layer multiuser scheduler like in the high speed downlink packet access scheme included in 3GPP WCDMA Release 5 specification the overall channel utilization can be improved.

متن کاملThe Central Limit Theorem for the Normalized Sums of Extended Sliding Block Codes from Sequences of Markov Chains with Time Delay
We extend the sliding block code in symbolic dynamics to transform two sequences of Markov chains with time delay. Under the assumption that chains are irreducible and aperiodic, we prove the central limit theorem (CLT) for the normalized sums of extended sliding block codes from two sequences of Markov chains. We apply the theorem to evaluations of bit error probabilities in asynchronous sprea...

متن کاملOptimal binary communication with nonequal probabilities
Optimal signal energies are derived for optimal binary digital communication systems with arbitrary signal probabilities and correlation with both coherent and noncoherent detection. The resulting bit-error probability (BEP) is computed and compared with the BEP of the same systems with equal signal energies. One of the conclusions is that for the coherent system with nonegative correlation, an...

The complexity in the hardware implementation of traditional optical code-division multiple-access correlation receivers with double optical hardlimiters is discussed. A comparison with the implementation of recently proposed chip-level receivers is presented as well. In addition, the bit error probabilities and the throughput capacities for both chip-level and correlation systems (without hard...
