    • A linear systolic array is added to the lower side of a trapezoid systolic array created by combining a triangular systolic array and a square systolic array. In order to make the connection among the cells fixed, the intermediate result output from each row of the trapezoid systolic array to a lower row is shifted in phase with respect to the intermediate result of the complex MFA algorithm, the phase shift is absorbed by the next row, and the phase shift in the intermediate result output from the last row of the trapezoid systolic array is corrected by the linear systolic array. Each cell is implemented by a CORDIC circuit that processes vector angle computation, vector rotation, division, and multiply-and-accumulate with a constant delay.

    • Disclosed is a signal processing system in a base station that receives and processes single carrier or multiple carrier signals from transmitting units in a sectored coverage area with at least one transmit antenna and at least one receive antenna, the signal power gain between transmit and receive antennas within each sector being represented as a channel matrix with path gains. The system comprises: a detection unit that determines if signals from a given target transmitting unit is available in the signal received in a sector, and generates a detect signal for a combination unit; a decision unit that selects size of interference cancellation matrix; and an interference cancellation unit. When the signal from detection unit indicates that signal from a target transmitting unit is in the signal associated with at least two sectors, the decision unit joins channel matrices associated with the sectors to generate a large channel matrix, and using the resulting large channel matrix, the interference cancellation unit eliminates interference or generates originally transmitted signal. When the signal from detection unit indicates that signal from a target transmitting unit is in the signal of only one sector, the interference cancellation unit eliminates interference from the received signal, using the channel matrix associated with the one sector.

    • The present invention provides an apparatus and a method that realize dynamically processing signals received from multiple sectors to increase throughput of uplink communications in a multi-sectored wireless base station. The signal streams received from sector-1 (25) and (26) and signal streams received from sector-2 (27) and (28) are concentrated in a unit (105). Similarly, channel parameters (29) and (30) from sector-1 and sector-2, respectively, are used to create a modified channel matrix, dimension of which is much larger than that of each of channel matrices of respective sectors. Dynamic processing of signals received from multiple sectors is done by a detection unit (103) which receive channel parameters (131) or (133), and, a comparison unit (104). Signals from a transmitting unit are detected within the signals received from two or more sectors, or the same signals are detected within the signal received from one sector. Based on the results of the comparison unit (104), a modified channel matrix and received signal vector from one sector is selected in a channel matrix selection unit (102) and used in a unit (21) to perform interference cancellation.
