- Programme manager: MSc Communications and Signal Processing
Digital signal processing (DSP) - the mathematical manipulation of an information signal to modify or improve it in some way - is the underlying technology that makes possible, not just today's advanced communication devices, but virtually every aspect of our modern lives. These include the mathematical algorithms which implement the active suspension in today's cars or control a Boeing 777 airplane, as well as the speech codec inside a mobile phone, MPEG video compression and an MRI machine. Without DSP, we would have no televisions, no radar, no cameras, no WiFi and no Internet, in fact normal existence would cease!
So it was my passion for both mathematics and communications that attracted me to use DSP, first as a radar research and development engineer in industry and later pursue a PhD in signal processing at Imperial College, London. Now, many years later, I still feel the same sense of excitement lecturing on the new DSP algorithms which now power modern broadband communication systems. And we try to maintain that excitement in this MSc, through research-inspired teaching, relevant industrial lectures and modern cutting-edge student projects. Finally, to quote one ex MSc student: "Since graduating, I have worked on the image processing algorithms that make digital cameras possible, designed mathematical methods to enhance GPS devices and developed the signal processing for the new small, low-power cellular femtocells. None of this would have been possible without the DSP theory that I learnt here at Leeds." Now that really made my day!
