In existing LoRa implementations, challenges such as low transmission power, unknown channel conditions, and degraded received signals lead to suboptimal decoding performance. To overcome these issues, we propose ZCLoRa, which leverages the Zak transform and exploits its sparse representation capabilities, enabling effective signal denoising. The Zak-transformed signal is processed by a convolutional neural network (CNN) for enhanced symbol decoding. We evaluate the performance of ZCLoRa in terms of symbol error rate (SER), showing significant improvements in decoding accuracy while maintaining the low complexity and power efficiency essential for IoT devices. Furthermore, we validate our model on USRPs, providing empirical evidence of its real-world effectiveness.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 4","pages":"839-842"},"PeriodicalIF":3.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By letting a MLO capable STA to alternately adopt increasing and decreasing CW updating rules for links when activating links for channel contention, the advantages of both adopting a small CW and adopting a large CW can be obtained, thereby benefiting the latency performance of WLANs.

To reap their synergic gains, this letter investigates a STAR-RIS aided communication system with MAs to maximize the ergodic sum-rate of multiple users by exploiting statistical channel state information (CSI). To tackle this problem, an efficient algorithm based on the alternating optimization (AO) and fractional programming (FP) framework is proposed to jointly optimize the transmission and reflection coefficients (TRCs) at the STAR-RIS, the beamformer, and the positions of MAs at base station.

However, conventional PE algorithms often assume a constant or slowly varying channel, limiting their effectiveness in rapidly changing environments. In this letter, we propose a transformer-based deep PE network specifically designed for time-varying channels. To compensate for carrier frequency offsets (CFOs), we incorporate an adaptive parameter correction module. Moreover, the network implements a pre-extractor to capture multi-scale channel features, enabling it to handle time-varying conditions effectively. Simulations demonstrate that the proposed method achieves performance comparable to orthogonal frequency division multiplexing (OFDM) systems while significantly reducing pilot overhead.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 5","pages":"893-897"},"PeriodicalIF":3.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the reliability difference between the index and modulated layers in GCI-DCSK, we develop a dual-level polar-coded modulation (DLC-PCM) scheme that provides unequal error protection (UEP). Furthermore, to better manage the reliability differences among index bits in the GCI-DCSK system, we propose a dual-level bit-interleaved polar-coded modulation (DLC-BIPCM) scheme by incorporating a bit-interleaved coded modulation (BICM) structure within the index layer. Additionally, we derive log-likelihood ratio (LLR) expressions and calculate the capacities of both the index and modulated layers to strategically guide the design of the DLC-PCM scheme. Simulation results demonstrate that our proposed polar-coded approach achieves superior bit error rate (BER) performance and lower complexity compared to existing low-density parity-check (LDPC)-based schemes.","PeriodicalId":13197,"journal":{"name":"IEEE Communications Letters","volume":"29 4","pages":"804-808"},"PeriodicalIF":3.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
