    Abstract: Data is to be estimated from a received plurality of data signals in a code division multiple access communication system. The data signals are transmitted in a shared spectrum at substantially a same time. A combined signal of the transmitted data signals are received over the shared spectrum (42) and sampled (43). A channel response for the transmitted data signals is estimated. Data of the data signals is estimated (44) using the samples and the estimated channel response. The data estimation uses a fourier transform based data estimating approach. An error in the data estimation introduced from a circulant approximation used in the fourier transform based approach is iteratively reduced.

    Abstract: In a wireless digital communication system which may employ CDMA 5 technology, a method and system for obtaining channel quality (CQ) measurements for downlink resource allocation wherein a User Equipment (UE) continuously measures RSCP based on a communication on a reference channel provided by the network. The UE measures timeslot ISCP either continuously, by configuration or by rotation and reports downlink CQ. The UE may report the 10 RSCP once and the ISCP per timeslot, or may report some function of the RSCP/ISCP ratio such as modulation parameters or combined coding of all timeslots. 3/3 50UE 1 BASE STATION L0 UE 12 STEP 54 MEASUREMENT OF ROVER A STEP 52 STE ~RSCP REFERENCE STEP 56 MEASUREMENT REPORT RECEIVE STEP 58 -+ WNNKT CQ -- DOWNUNK CQ STEP 60 MEASUREMENT MEASUREMENT TO DETERMINE STEP 62 REQUIREMENTS FOR TRANSMIISION TO FIGa 3 VE

    Abstract: Se recibe una pluralidad de senales de datos en el receptor. El receptor mide una respuesta de canal asociada con las senales de datos transmitidos. Se determina una respuesta del sistema. La respuesta del sistema se expande para que sea ortogonal por tramo. Las senales de datos se recuperan en base en parte a la respuesta del sistema expandido.

    Abstract: La presente invencion se refiere a un dato que va a ser detectado en un sistema de comunicacion inalambrico. Se reciben una pluralidad de senales de comunicacion (r). Se modela una solucion para estimar datos (d) de las senales de comunicacion recibidas (r) utilizando un sistema lineal (34) que requiere una inversion de matriz. Se determinan las columna o hileras (A, y B) de un factor de Cholesky aproximado. Se determina una diferencia entre las columnas o hileras determinadas (A, y B). Si la diferencia determinada es menor que un umbral, se determinan las columnas o hileras subsecuentes por las columnas o hileras previas determinadas. Se estima el dato (d) de las senales de comunicacion recibidas (r) utilizando el factor de Cholesky aproximado.
