    Abstract: PROBLEM TO BE SOLVED: To reduce complexity in detecting data at high speed. SOLUTION: K data signals are transmitted over a shared spectrum. A composite signal is received and sampled over the shared spectrum (48). The composite signal has the K transmitted data signals (48). A composite channel response matrix is generated (49) using a code and an impulse response of the K transmitted data signals. A block column of a composite channel correlation matrix is determined using the composite channel response matrix (50). Each block entry of the block column is a K by K matrix (51). At each frequency point k, the K by K matrix is determined by taking the Fourier transform of the block entries of the block column (52). An inverse of the K by K matrix is multiplied to the result of the Fourier transform (52). Data are retrieved from the K data signals using an inverse Fourier transform (55).

    Abstract: PROBLEM TO BE SOLVED: To provide a MIMO (Multiple-Input Multiple-Output) system which is different from prior systems and equalizes received multi-path components.
    SOLUTION: Data is transferred in a wireless communication system, such as a wireless spread spectrum communication system. Data is encoded to produce a plurality of data streams. For each of a plurality of transmitting antennas 34, the data streams are used to produce a vector for transmission. Each transmission vector is transmitted by its transmitting antenna through a wireless air interface experiencing multipath. Multi-path components from each transmitted transmission vector are received by a plurality of receiving antennas 36. The received multi-plath components are equalized to recover the transmission vectors. The data are recovered from the recovered transmission vectors.
