This program is used for simulation signal mean square error of the Kalman filter

For this experiment introduced new concepts regarding the implementation methods of IPC. Through the use of signals was possible interruptions. And with the use of shared memory, it was possible to make calls between processes, by sending signals. The use of signals requires a signal handler, who treats upon arrival. The use of the program becomes asynchronous signals, which require more care during handling of the instructions. Experiment 1 allows learning about creation of concurrent processes in the Operating System (OS) Unix. However, the creation process is not at all helpful. There are applications that require that there be some method that enables the sharing of data (information) between processos.x
