This volume presents the proceedings of the first French-Israeli Workshop on Algebraic Coding, which took place in Paris in July 1993. The workshop was a continuation of a French-Soviet Workshop held in 1991 and edited by the same board. The thoroughly refereed papers in this volume are grouped into parts on: convolutional codes and special channels, covering codes, cryptography, sequences, graphs and codes, sphere packings and lattices, and bounds for codes.
