Problem Statement A short-range wireless calculator service should be developed. The product is a group of MATLAB functions that implement this wireless service. The final product shall be supplied as a group of m-files that can be run as Transmitter/Receiver on a standard computer. The hardware platform consists of two standard computers and two headsets. The headsets are placed next to each other and connected to one PC each. The wireless service should use the acoustic channel between the headsets as the only communication link between the computers. Platform Specifications Report Writing Tool: LaTeX Specific Requirements Two integer numbers separated by one of the 4 basic arithmetic operations (addition, subtraction, multiplication and division) will be typed on one keyboard. The message should be wirelessly transmitted to the second computer, which should transmit automatically the result back to the first computer. If errors are detected at any point of the transmission, some re-transmission system must be implemented. The result should be displayed on the screen of the first computer in less than 10 seconds after pressing "Enter". The distance between headsets shall be 5 cm. All stages of volume control, e.g. volume control on headset and all internal PC software control, shall be on max level. The minimum and the maximum values for the numbers involved in the operation are 0 and 1000. If the second computer is not able to answer the question (due to noise/interference),a retransmission should be requested. The same operation will be re-typed and re-transmitted. .
