This paper considers error minimisation of a MIMO transmission system over frequency-selective (FS) channels. A non-linear precoding scheme with adaptive bit loading is proposed to minimise the average BER for a given target data rate. The proposed design utilise the recently developed polynomial singular value decomposition (PSVD) that decouples the FS MIMO channel into a number of independent FS SISO subchannels with different gains. Different from our previous work which assumes a heuristic bit loading, the work presented here allocates the transmission bits over the resulting FS SISO subchannels adaptively according to their SNR conditions. Simulation results show that better BER performance can be achieved for different data rate targets compared with both heuristic and uniform bit loading.
