Abstract: This disclosure provides a data-driven and scalable method to discover cause-and-effect relationships in data from natural systems that include sparse data sets. This technique can learn a causal graph from heterogenous data sources by combining embeddings from real data and embeddings from simulated data generated by process-based models. The causal graph is used for what-if analysis in out-of-distribution settings. One application is understanding the factors that affect soil carbon. A causal model created by these techniques can be used to discover cause-and-effect relationships that affect soil carbon. This model has applications such as forecasting soil carbon for a future time point to help inform farm practices. Farm practices, like tilling, may be modified in response to predictions provided by the model.

Abstract: Traceability of agricultural activities is very critical to market compliance. Mere automation of traditionally monitored agricultural activities alone may not address the challenge of providing a simple yet flexible and predictable method of effective and real time monitoring of agricultural activities around the farm that may be used to compute crop protocol for any crop under consideration. The systems and methods of the present disclosure facilitate automatic identification of crop protocol irrespective of the type of the crop and agricultural activities associated thereof. Real time monitoring of the agricultural activities also enable farm personnel to conclude on effects of dynamic changes in crop protocol thereby allowing continuous building up of the repository of agro-climatic zone based information associated with the farm. Regulating crop protocol results in a predictable increase in efficiency and sustainability of crop yield that helps farm personnel to optimize productivity.

Abstract: A symbol boundary in a data packet having a guard interval preceding a preamble having a predetermined sequence of symbols is detected by receiving a signal representing a data packet; sampling the received signal at a sampling rate; estimating channel impulse responses from a set of samples in dependence on the predetermined sequence of symbols of the preamble; determining an energy value for each of a plurality of windows of channel impulse responses, each of the windows corresponding to W number of consecutive samples, the energy value for each of the windows being indicative of the total energy associated with the channel impulse responses of that window; determining which of the windows has the greatest energy value; and identifying the earliest sample of the consecutive W samples in said determined greatest energy window, the earliest sample being indicative of a symbol boundary for the preamble.

Abstract: The method and system for a computer implemented agricultural activity monitoring and training is described herein. The system comprises a plurality of sensors to sense the agriculture activities and environment parameters to generate sensor data. A transceiver presents in the system transfer the sensor data to the server. The server comprises a activity detection module to detect the agriculture activities performed by an individual. A monitoring feedback generator to generate a monitoring feedback based on detected activity. A remote training module determines a performance score of the activity performed by the individual and sends training feedback to the individual based on the performance score.

Abstract: A method and processing block for receiving data transmitted in a MIMO system is provided. Data is transmitted as a transmit vector of values from multiple transmitting antennas and received as a receive vector of values at multiple receiving antennas. Candidate vectors are determined based on each of a plurality of constellation points of the constellation configuration used in the transmission scheme. A channel matrix is decomposed into a unitary matrix and a triangular matrix, such that a relationship links: (i) a function of the unitary matrix and the receive vector, and (ii) a multiplication of the triangular matrix and the transmit vector. A best candidate vector from the set of candidate vectors is utilized for the computation of soft bits representing the values of the transmit vector.

Abstract: The present disclosure provides methods and systems for automatic gain control (AGC) in a multiple input multiple output (MIMO) system having two or more receiver chains, each receiver chain including a receiver and an AGC module. The AGC system accepts a signal at a compensation module associated with the receiver chain and calculates one or more gains using the AGC module associated with the receiver chain. Then, an estimation module computes a scaling factor for each receive chain from the gains and transmits the scaling factor to the compensation module of the respective receiver chain, which requantizes the signal based on the scaling factor.
