Space-time block coding (STBC) improves the transmission performance of the MIMO communication system, but it also leads to high complexity at the receiver. In this paper, we propose a simplified detection algorithm using PAM decomposition of CPM for space-time block coded minimum frequency shift keying (STBC-MSK) transmission system. Intrafix symbols are inserted after the information bits to maintain the continuity of phase, and Laurent decomposition representation of MSK is performed on the signal before STBC, and matched filtering is used instead of maximum likelihood sequence detection (MLSD) at the receiver. Analysis and simulation results show that this simplified detection algorithm efficiently reduces the computation complexity with a very small degradation in error performance compared withthe conventional MLSD.

the article examines the main stages of the liberalization of foreign economic activity in Uzbekistan, analyzes the features of the formation of a new policy at the present stage of development, characterizing the strengths and weaknesses of each of the stages passed. For this purpose, an overview and generalization of key provisions in the research of leading theoretical schools and directions in the field of foreign economic activity planning, logic and stages of strategic management of this process both at the meso and at the macro level is presented. the scientific novelty of this article lies in the comprehensive study of the theoretical and methodological foundations for the development of foreign economic activity (FEA) in Uzbekistan; theoretical substantiation of the feasibility and identification of specific features of the transition to innovative development of the foreign economic complex in the context of globalization. As a result of the study, the key function of the state in the development of foreign economic activity is revealed, the content side of which is a set of tools that ensure the harmonization of the interaction of methods and regulatory tools, which consists in realizing competitive advantages at the international level, ensuring the country's active participation in the system of world economic relations. In the conclusion, it is concluded that a correctly selected foreign economic policy has created conditions for the growth and development of the economy not only within the framework of the state, but also for the country's entry into world markets.

Identification of Breast Cancer cells as Benign or Malignant is an important task for the early stages of Cancer to reduce fatality caused by it. Using Machine learning, we can predict the type of cancer, which allows us to provide better treatment. To classify the tumors, we use 7 different models such as Logistic Regression, Decision Tree Classification, K-Nearest Neighbors, Stochastic Gradient Descent, Support Vector Machine, Gaussian Naive Bayes and Random Forest Classification. these models are then compared on various evaluation metrics such as Accuracy, Precision, Recall and F1-Score to choose the best model for the prediction. this way the data is analyzed and misdiagnosis in the future can be prevented.

Genetic algorithms can be used in combination with multi-agent monitoring and data collection technologies for compiling and adjusting the dynamically changing work schedule of an economic entity with complex internal infrastructure. In this case, the important issue is the quality of the drawn-up schedule and its monitoring. the article reviews the possibility of applying the method of randomized summary indicators for assessing the quality of the compiled and dynamically adjusted service schedules for ships in the seaport.
