Abstract
This paper describes a new resolution method concerning the orthogonality equations of oversampled complex modulated filter banks, and it is illustrated in the context of oversampled OFDM/QAM modulations. A first simplification is related to the introduction of an equivalent system of orthogonality equation of reduced size. Its solution is expressed using different sets of angular parameters. Furthermore, a compact representation, we recently introduced for OFDM/OQAM modems, is adapted in order to accurately represent the angular parameters of the OFDM/QAM modulation. Both simplifications allow the design of OFDM/QAM modems corresponding to rational oversampling factors and having a high number of carriers.
