Abstract: This paper is of interest to anyone who is responsible for operating and maintaining a DVB-T (COFDM) transmitter. We examine the OFDM Transmitter starting with the interface to the exciter. We look at data randomizing, Reed-Solomon Coding, Convolutional encoding, Trellis encoding and Viterbi Decoding. Each scheme is described in a simplified matter so the audience will have an understanding how each works. We then explore testing and monitoring methodology and examine how distortions common to the RF sections of a transmitter effect the OFDM signal. The paper also looks at hardware and describes how the manufactures have designed their transmitter. The final part of the paper looks at the recommended DVB-T measurements required to assure optimum performance and coverage, how these measurements should be made, and what is acceptable performance.
