| Abstract (ENG): |
Digital broadcast systems such as Digital Video Broadcasting - Handheld (DVB-H) support Single Frequency Networks (SFNs). Within these SFNs, all transmitters broadcast the same signal on the same frequency and therefore represent a single big network 'cell'. However, even SFNs have borders, and some DVB-H networks are built in a cellular scheme where one cell is covered by a single transmitter. In the border region between two of these cells, signal quality available from either of the cells is usually poor. This paper presents an approach to realize diversity reception of the signals of two or more different adjacent network cells in such a border region. By this means, the packet error rates of services available in several cells may be reduced significantly by replacing lost packets from an alternative signal. It is shown in this paper how such an approach may be implemented with the DVB-H standard by making use of a single receiver front-end only. With this technique, also soft handovers on packet level become possible. |
