WebAbstract—We compare the capacity of dirty-paper coding (DPC)to that of time-division multiple access (TDMA)for a multiple-antenna (multipleinput multiple-output (MIMO)) Gaussian broadcast channel (BC). We find that the sum-rate capacity (achievable using DPC)of the multiple-antenna BC is at most @ A times the largest single-user capacity (i.e ...

Webderived in [1] and shown to be achieved using Dirty Paper Coding (DPC). Later, in [2], it was shown that the DPC rate region coincides with the capacity region. Practical code designs for DPC have been studied in [3]–[7]. In the designs in [3]–[6], joint shaping and coding encoders (or iterative decoders) are required at the transmitter (or ...
