Decoder Assisted Channel Estimation and Frame Synchronization
نویسنده
چکیده
In regards to turbo codes, to the author's knowledge, previous literature has treated decoder assisted frame synchronization and channel estimation as separate processes. Here a joint decoder assisted process of channel estimation and frame synchronization is proposed. In brief, the method entails using a sync word (SW) embedded mid-packet for both channel estimation and frame synchronization. The method will use a correlation-based frame synchronization that passes a list of possible delays to the turbo decoder. The turbo decoder will draw upon pilot symbol assisted modulation (PSAM) techniques for channel estimation using the coded SW.

Code-aided ML joint delay estimation and frame synchronization
We present a novel maximum-likelihood (ML) algorithm for joint delay estimation and frame synchronization. The algorithm operates on coded signals, and exploits the code properties by accepting soft information from the MAP decoder. Issues of convergence are addressed and we show how computational complexity may be reduced without any performance degradation. Simulation results are presented fo...
متن کاملImproved Iterative Channel Estimation and Turbo Decoding Over Flat-Fading Channels
In this paper, we discuss the influence of imperfect Wiener channel estimation on performance and dynamics of a turbo decoder using the non-linear soft data feedback. We show that the correlation between the channel estimates and soft bits produced in subsequent iterations can lock the turbo decoder in a wrong minimum and create a high error floor. This problem can be circumvented by a differen...
متن کاملA Synchronization Scheme Based on Decoder Soft Outputs of Ldpc Codes over Hf Channels
A frame synchronization scheme based on decoder soft outputs of low-density parity-check codes over high frequency channels is considered. In a coded orthogonal frequency division multiplexing based system, low-density parity-check code decoder soft outputs are exploited in order to perform frame synchronization. The decoder soft outputs are observed for several candidate frame start positions ...
متن کاملTime-Varying Block Codes for Synchronization Errors: MAP Decoder and Practical Issues
In this paper we consider Time-Varying Block (TVB) codes, which generalize a number of previous synchronization error-correcting codes. We also consider various practical issues related to MAP decoding of these codes. Specifically, we give an expression for the expected distribution of drift between transmitter and receiver due to synchronization errors. We determine an appropriate choice for s...
متن کاملAn Algorithm for Iterative Decoding and Channel Estimation of Space-time Coded Fh Systems
This paper proposes an algorithm for joint decoding and channel estimation (JDE) of frequency-hopping (FH) system employing space-time (ST) codes. The channel is modeled as a block fading channel, where the fade is constant during each hop and independent from other hops. The algorithm is based on quantizing the fading process, such as done in Markov fading models. The algorithm is semiblind, w...
