In this contribution, transmit power allocation schemes for BER performance improvements in a wavelet-based multicarrier transmission system with SVD (singular value decomposition) equalization are investigated under the constraint of a limited total transmit power. Contrary to other contributions, here the transmit power is not only adapted to the subchannels but rather to each symbol of the SVD equalized data block individually. Based on the Lagrange multiplier method different solutions are investigated. In order to obtain numerical results, the schemes are exemplarily applied to different radio channel characteristics including Rayleigh and Rice distributed path coefficients
