Abstract: Please Note. This abstract contains mathematical formulae which cannot be represented here. Bounds for exponential sums over finite fields and Galois rings are combined with Lagrange interpolation to obtain bounds on the peak-to-mean envelope power ratio (PMEPR) of a variety of OFDM coding schemes obtained from trace codes. This class of codes includes the binary simplex code, duals of binary, primitive BCH codes and a variety of their Z2e- analogues.

This report is superseded by HPL-1999-51.
