This paper proposes an iteratively enhanced semantic receiver for natural-language text transmission over noisy wireless channels using multiple short block codes. At the transmitter, each sentence is permuted by a character-level interleaver, partitioned into segments, and independently encoded by short block codes. A...

Existing deep joint source-channel coding (JSCC) methods typically employ uniform resource allocation across spatial regions, which may lead to spatially imbalanced reconstruction quality under limited channel resources. To address this, this paper proposes AgentJSCC, a difficulty-aware transmission framework. Specific...

Conventional orthogonal frequency division multiplexing (OFDM) channel estimation relies on single-tap estimation and time-frequency (TF) interpolation, which becomes unreliable in high-mobility channels because Doppler-induced intercarrier interference (ICI) invalidates the underlying elementwise TF model. This paper...
