Abstract: I describe an algebraic approach to the design of a family of line codes for parallel transmission of b bits over b+1 wires that admit especially simple encoding and decoding algorithms. The resulting codebook is a geometrically uniform subset of a Permutation Modulation codebook. With these codes, resistance to common-mode noise is obtained by using codewords whose components sum to zero, simultaneous switching output noise is reduced by using constant-energy signals, and the effects of intersymbol interference are reduced by having decisions based on only two values at the input of the final slicers. Codebook design is based on the theory of Group Codes for the Gaussian Channel, as specialized to Coxeter matrix groups generated by reflections in orthogonal hyperplanes. I also discuss the introduction of error control coding in a way consistent with the constraints imposed on that design.  (Work done with Emanuele Viterbo and Michele Elia.)
