Fourier Transform and Its Application in Cell Phones
      Anupama Gupta
Abstract: Communication is all based on Mathematics, be it digital, wired or wireless. Signal transmission is done through modulation i.e. amplitude modulation (AM), frequency modulation (FM) or phase modulation (PM). At the receiving end the transmitted signal is demodulated to extract the information. All these techniques are based on pure mathematics. While modulating the information signal, a high frequency sinusoidal carrier signal is used to transmit the message signal through a medium (cable or air). It is then received and demodulated using Fourier Transform analysis. So for understanding the communication technology, the processes of modulation, demodulation and Fourier Transform need to be explored first. In this paper, I have discussed how Fourier Transform is used in cell phone networking. Mathematics Subject Classification: Primary 94B12; Secondary 90B18
