Improving performance of coherent coded It can be shown that if the channel estimates are perfect(a1=a1, a2 OFDM systems using space time transmit a2)diversity can be achieved
Introduction to Insulated Gate Bipolar Transistors Prepared by: Jack Takesuye and scott Deuty Motorola inc INTRODUCTION As power conversion relies more on switched applications The IGBT is, in fact, a spin-off from power MOSFET
