Abstract

A multiresolution transmission scheme is proposed in which the different data is transmitted from separate incoherent transmitters possibly located at different locations. This scheme permits a backward compatible upgrade of an existing system. The different data streams are transmitted at different power levels, that is power division multiplexing is used. A multistage receiver which performs successive cancellation is proposed to extract the data. For each transmitter QPSK modulation is considered.
