Turbo-like Codes are Good for the Block-Fading Channel

چکیده
This paper studies turbo-like coded modulation in the block-fading channel. In particular we show that the performance of such coded modulation schemes is close to the information outage probability of the channel for any block length, as opposed to standard coded modulation schemes based on trellis-terminated convolutional codes. For large block length, asymptotic performance of the proposed structure is given by the distribution of its decoding threshold. By using asymptotic weight enumerator techniques, we derive the asymptotic maximum-likelihood performance of the proposed codes.

On improved bounds on the decoding error probability of block codes over interleaved fading channels, with applications to turbo-like codes
We derive here improved upper bounds on the error probability of block codes which are transmitted over fully interleaved Rician fading channels, coherently detected and maximum likelihood decoded. We assume that the fading coefficients during each symbol are statistically independent (due to a perfect channel interleaver), and that perfect estimates of these fading coefficients are provided to...
متن کاملPerformance and Design of Turbo Codes on Rayleigh Fading Channels
Fading in wireless environments is a major obstacle to reliable communications. In order to mitigate the e ects of fading, channel coding is often employed. In this thesis, the performance and design of the channel coding technique, turbo codes, [1] is examined over Rayleigh fading channels. The thesis considers coherent BPSK signaling over both time-correlated and fully-interleaved Rayleigh, s...

In this paper we study adaptive power allocation (PA) policies for improving the performance of convolutional and turbo codes on fading channels. The transmitter has an average power constraint. The fading process can he continuous (e.g. Rayleigh distribution). Perfect channel state information at the transmitter (CSIT) and the receiver (CSIR) are assumed. For convolutional codes, we consider b...

Channel coding is one of the techniques used for suppression of fading and channel noise effects. Most of the researches on channel codes have been focused on the codes which are defined on Galois fields. Since two decades ago, using channel codes defined on Real and Complex fields has been considered for joint sourcechannel coding in multimedia transmission; but most of the works have focused ...
متن کاملComparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes
Turbo equalizers have been shown to be successful in mitigating the effects of inter-symbol interference introduced by partial response modems and by dispersive channels for code rates of 1 2. In this contribution, we comparatively studied the performance of a range of binary phase-shift keying turbo equalizers employing block-turbo codes, namely Bose–Chaudhuri–Hocquenghen turbo codes, convolut...
