In the face of increasing complex large-scale digital design, universal verification methodology (UVM) has become the mainstream verification method due to its scalability, standardization, portability and other characteristics. Orthogonal frequency division multiplexing (OFDM) is an advanced multi-carrier transmission technology, which is widely used in the field of wireless communication. This paper presents a verification framework of OFDM baseband processing system based on UVM. UVM generates random excitation and passes it to our design, and automatically collects the results and compares them with the reference model to achieve sufficient verification of the system. Simulation results show the final functional coverage reaches 100%, demonstrating the validity of our verification framework.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126141789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Error correcting codes (ECC) are the most common ways to protect memories from MCU attacks. In this paper, a low redundancy ECC method for two-dimensional matrix-based code is presented, which is called horizontal-vertical-diagonal-block (HVDB) code. The proposed method employs the change information of parity bits on the horizontal direction, vertical direction, diagonal direction and data block of the two-dimensional matrix to detect and correct errors. Through analysis and experiment, it was demonstrated that this method, compared to previous methods for correcting 2-bit errors, has fewer redundancy and a reduced decoding overhead.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130800592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The array flow pattern similar to ULA was synthesized by phase mode excitation transformation. Theoretical analysis and simulation experiments show that, under the same conditions, compared with the uniform circular array, the proposed reciprocal circular array has a higher resolution of similar sources.

There exists a problem that non integer oversampling of signal can cause big jitter in both transmitter and receiver. In transmitter, this research reduces jitter by replacing the traditional digital interpolation with a new module which includes interpolation, shaping filtering and decimation. Moreover, in receiver, timing offset estimation module and symbol interpolation module are added. The previous module estimates the normalized timing error value in the non-spread spectrum branch and then the latter module uses the symbolic interpolation operation to realize accurate timing synchronization in the situation of low oversampling rate. In this way, the stability of locked loop in receiver can be guaranteed. We also verify the feasibility and the performance of this method by simulating on MATLAB. An advantage of this method is that joint demodulation of TT&C link and data transmission link can be realized only utilizing the stable cumulant of NCO phase of delay locked loop based on the characteristics of precisely aligned coupling of UQPSK-DSSS signal.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132560420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the IKP features positioning is not accurate and hand information utilization is insufficient, this paper proposes a new identification method based on the geometric features of the IKP. First, the collected palm images are preprocessed, and the fingertips position are located by the improved center of gravity distance method. Next, the finger valley points and the reference points of the IKP are detected by using the gray gradient changes, and then the ROI (regions of interest) of the IKP are determined, Harris corner detection and K-means clustering algorithm are used to locate the centroid positions of each ROI, and 20 feature quantities for identification are constructed from the geometric features of the 12 centroids and the 4 fingertips. Finally, Knearest neighbor algorithm is used to calculate Euclidean distance of the features for feature matching. In order to verify the method proposed in this paper, a self-built small database is used for testing, and the experiment result show that the recognition rate is 98.39%, which verifies the feasibility and effectiveness of this method.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129051472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
