| description | Procedimiento similar a CORDIC de valor complejo para tareas de procesamiento de señales que pueden reducirse a un problema de cuadrado mínimo con al menos una condición secundaria lineal, - en el que la condición secundaria lineal está incluida en el problema de cuadrado mínimo que debe resolverse, formulado como una eliminación parcialmente Gaussiana con la ayuda de un complemento de Schur, - en el que el problema de cuadrado mínimo es resuelto por medio de una disección QR por un algoritmo, utilizando las transformaciones Gaussianas lineales y las rotaciones de Givens del circuito, y - en el que el algoritmo es ejecutado sobre un campo triangular superior de procesadores y se tienen en cuenta las condiciones secundarias al menos en una etapa de trabajo dentro del campo de procesadores.
The invention relates to a complex-valued CORDIC-like method for signal processing tasks which can be put down to a least square problem with at least one secondary condition. An algorithm is implemented on a processor field (1). The aim of the invention is to prevent upstream calculating steps for calculating secondary conditions. To this end, the secondary conditions are considered in at least one working step within the processor field, whereby entire complex-valued signal processing in uniformly built real CORDIC-based cells is preferably carried out. The invention correspondingly relates to a radio-communications system for carrying out a complex-valued CORDIC-like method for signal processing tasks. Said system is provided with at least one transmitting and receiving station, especially base station, which is provided with a plurality of dipole antennas (2) in any spatial arrangement and a processor field (1) which is provided with a plurality of front inputs for receiving antenna signals of the plurality of dipole antennas (2) and a plurality of outputs (4) for outputting N complex data streams with baseband information of N incident signals. |
