Performance of Reed-Solomon codes for hybrid-ARQ over Rayleigh fading channels under imperfect interleaving
نویسندگان
چکیده
We present a new method to analyze the performance of Reed-Solomon codes for hybrid-ARQ over Rayleigh fading channels with imperfect interleaving. Using the asymptotic results of level crossings of the faded envelope, we characterize the packet error probability as a function of the Doppler frequency and mean signal-to-noise ratio (SNR). We then use the notion of equivalent Doppler frequency to include the effect of imperfect interleaving on performance. This approach allows us to directly evaluate the throughput of hybrid-ARQ schemes and also specify minimum interleaving depths for achieving optimum throughput on correlated Rayleigh channels.

Robust Vb 2d-celp Image Transmission over Cdma Fading Channels
| This paper describes a new error resilient analysis{by{synthesis coding scheme and its application for robust still image transmission over DS-CDMA Rayleigh fading channels. The channel uses Reed-Solo-mon (RS) outer codes concatenated with Convolutional inner codes, and truncated type-I hybrid ARQ protocol based on the selective repeat strategy and the RS error detection capability.
متن کاملPerformance of Reed Solomon Error-Correcting Codes On Fading Channels
In this paper, our aim is to evaluate the performance of Reed Solomon (RS) codes when used to protect Asynchronous Transfer Mode (ATM) cells (424 bits) over fading channels. The well-known GilbertElliott model (GE) represents the memory-fading channel. Its parameters like transition probabilities are related to physical quantities associated with fading statistics (Doppler normalized frequency,...
متن کاملHybrid ARQ using Serial Concatenated Convolutional Codes over Fading Channels
In this paper, we propose and analyze a new hybrid FEC/ARQ scheme using rate compatible punctured serial concatenated convolutional codes (SCCCs) which is suitable for flat-fading channels. Puncturing increases the transmitted code rate, and the rate compatibility criterion allows incremental redundancy to be transmitted after each decoding failure according to a code-combining type-II Hybrid A...

We analytically compare the word error probabilities of imperfectly symboland bit-interleaved block codes over GF(2m) on fading channels. We employ an approximate fading channel model of a two-state Markov chain, using statistics of the fadeand interfadedurations. The analytical method is based on a technique developed in [2]. Expressions are derived for two decoding strategies; independent bou...
متن کاملHybrid Type-II ARQ Schemes for Rayleigh Fading Channels
In this paper the throughput performance of Simple Automatic Repeat reQuest (ARQ) and Hybrid type-II ARQ schemes over Rayleigh fading channels are studied. Some new hybrid type-II schemes based on Rate Compatible Punctured Convolutional (RCPC) codes are proposed which can be regarded as a combination of simple ARQ and traditional hybrid type-II ARQ schemes. It is shown that the suggested scheme...
