More efficient STBC decoding is achieved with the help of orthogonal-triangular (QR) decomposition [7, 18].
While the key frames are Intra-encoded, this means without exploiting the temporal redundancy, the WZ frames are distributed encoded by using error correcting codes; for the WZ frames, the decoder generates the SI with the help of already decoded WZ and key frames, so-called reference frames.
In practice, the decision of whether the message is decoded successfully can be made with the help of a checksum (e.g. CRC) and we assume the relays which pass this checksum do not contain any errors in the decoded message.
Degree profile of the optimized LDPC ensemble: The optimization result of a target rate 0.5 is shown in Figure 4. We consider an inner differential code, operating at dB on a Rayleigh fading channel, and decoded using the noncoherent IDDD receiver with the help of using pilot symbols.
At the decoder, for the WZ frame decoding, auxiliary information should be decoded firstly and then SI is generated with the help of this auxiliary information by the spatial-aided motion-compensated extrapolation (SA-MCE).
At the decoding process, the downlink user uses joint maximum likelihood (ML) decoder to decode both downlink message and uplink messages with the help of side channel.
The decoding stage, i.e., determining the most probable state sequence given an observation, is performed with the help of Viterbi decoding procedure [31] which maximizes the a posteriori probability: {mathcal{S}}^{opt}=mathit{arg} {max}_{mathcal{S}}left( logPleft(mathcal{S}|{O}^{opt}right)right) (18).
Encoding and decoding at nodes in four phases are explained with the help of Table 1.
We ran Internet searches on Bakhtiyarov and Garkavenko, and, with the help of Google Translate, we decoded some of their writings in Russian, including a trail of Garkavenko's anti-Semitic blog posts.
