Coded Scma(編碼單片機)到底是什麼?
Coded Scma 編碼單片機 - Based on the simplified factor graph, the EC-IDD gradually reduces its complexity in each subsequent iteration, while improving the bit error rate (BER) performance, compared to the state-of-the-art joint detection and decoding (JDD) of polar-coded SCMA. [1]基於簡化的因子圖,EC-IDD 在每次後續迭代中逐漸降低其複雜度,同時提高誤碼率 (BER) 性能,與最先進的 Polar 聯合檢測和解碼 (JDD) 相比編碼的 SCMA。 [1]

In addition, the mapping strategy further optimizes performance of the polar coded SCMA while ensuring the power equilibrium for each user’s output signal. [1] Towards to the realization of massive machine type communications (mMTC) in Internet of Things (IoT), we propose a joint channel estimation and decoding (JCD) scheme to enhance the performance of polar coded SCMA system. [2] Thus, in this paper, we proposed a polarization weight (PW)-based polar coded SCMA (PC SCMA) system to satisfy the requirements of low complexity implementation and high reliability under a wide range of code length and rate. [3]此外,映射策略進一步優化了極性編碼 SCMA 的性能,同時確保了每個用戶輸出信號的功率平衡。 [1] 為了在物聯網 (IoT) 中實現大規模機器類型通信 (mMTC),我們提出了一種聯合信道估計和解碼 (JCD) 方案,以提高極性編碼 SCMA 系統的性能。 [2] 因此,在本文中,我們提出了一種基於極化權重(PW)的極化編碼SCMA(PC SCMA)系統,以滿足在寬碼長和碼率範圍內實現低複雜度和高可靠性的要求。 [3]

Towards to the realization of massive machine type communications (mMTC) in Internet of Things (IoT), we propose a joint channel estimation and decoding (JCD) scheme to enhance the performance of polar coded SCMA system. [1] Thus, BER performance of the proposed codebook design approach outperforms that of the existing codebook design schemes in both uncoded and coded SCMA systems, especially for large-size codebooks. [2] Additionally, we propose an adaptive turbo-coded SCMA system for mitigating the influence of multipath propagation so that the system's bits per symbol (BPS) throughput may be improved under favorable channel conditions by using the most appropriate near-instantaneous user load, modulation order and coding rate. [3] The performance of some of those constellations are evaluated for uncoded, high-rate, and low-rate LTE turbo-coded SCMA systems under different channel conditions through extensive simulations. [4] We then evaluate the performance of some of the well-known SCMA constellations for uncoded, high-rate, and low-rate LTE turbo-coded SCMA systems. [5] Numerical results depict performance gain in terms of Bit Error Rate (BER) and complexity over conventional LDPC coded SCMA systems. [6] Numerical results show that the designed codebook in an LDPC coded SCMA system can achieve lower PAPR while maintaining better performance and lower complexity than the traditional codebook. [7]為了在物聯網 (IoT) 中實現大規模機器類型通信 (mMTC),我們提出了一種聯合信道估計和解碼 (JCD) 方案,以提高極性編碼 SCMA 系統的性能。 [1] 因此,在未編碼和編碼的 SCMA 系統中,所提出的碼本設計方法的 BER 性能優於現有的碼本設計方案,特別是對於大型碼本。 [2] 此外,我們提出了一種自適應渦輪編碼 SCMA 系統,用於減輕多徑傳播的影響,以便在有利的信道條件下通過使用最合適的近瞬時用戶負載、調製階數和編碼率。 [3] 通過廣泛的仿真,評估了其中一些星座在不同信道條件下的未編碼、高速和低速 LTE Turbo 編碼 SCMA 系統的性能。 [4] 然後,我們評估了一些著名的 SCMA 星座在未編碼、高速和低速 LTE turbo 編碼 SCMA 系統中的性能。 [5] 數值結果描述了與傳統 LDPC 編碼的 SCMA 系統相比,在誤碼率 (BER) 和復雜性方面的性能增益。 [6] 數值結果表明,在 LDPC 編碼的 SCMA 系統中設計的碼本可以實現更低的 PAPR,同時保持比傳統碼本更好的性能和更低的複雜度。 [7]
