The Algebraic Space Time Codes (ASTC) are constructed based on cyclic algebras; they showed a good spectral efficiency, a full diversity, and a full rate under non selective channel condition. However, the radio - mobile channel is a selective channel whose features vary during the time. This selectivity is owed to the multi-path phenomenon and generates interferences between symbols (IES). The overall objective of this chapter is to proof that ASTC is adapted to channel selectivity, in order to analyze and improve its performances in wide-band system.

During the last 5 years, we have developed a seven-colour photometry at the Geneva Observatory. Our multicolour photo-electric system is of a wide-band type; the bandwidth being about 500Å for four filters. The three others are similar to theUBVsystem. In Table 1 we give the filter combinations used in our photometry (1).
