    Abstract: PROBLEM TO BE SOLVED: To provide frequency-independent eigensteering in MISO and MIMO systems.SOLUTION: A correlation matrix is computed for a MIMO channel based on channel response matrices and decomposed to obtain NS frequency-independent steering vectors for NS spatial channels of the MIMO channel. For main path eigensteering, a data symbol stream is transmitted on the best spatial channel for the main propagation path of the MIMO channel. For receiver eigensteering, a data symbol stream is steered toward a receive antenna based on a steering vector obtained for that receive antenna. For all eigensteering schemes, a matched filter is derived for each receive antenna based on the steering vector(s) and channel response vectors for the receive antenna.

    Abstract: PROBLEM TO BE SOLVED: To provide pilot transmission schemes suitable for use in wireless multi-carrier (e.g., OFDM) communication systems. SOLUTION: Pilot transmission schemes may utilize frequency, time or both frequency and time orthogonality to achieve orthogonality among the pilots transmitted by multiple base stations on the downlink. Frequency orthogonality is achieved by transmitting pilots on disjoint sets of subbands. Time orthogonality is achieved by transmitting pilots using a plurality of different orthogonal codes. The pilots may also be scrambled with a plurality of different scrambling codes, which are used to randomize pilot interference and to enable identification of transmitters of these pilots. Further, pilot interference is estimated and then subtracted from received symbols to obtain pilot-canceled symbols having improved quality. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide frequency-independent eigensteering in MISO and MIMO systems.
    SOLUTION: For principal mode and multi-mode eigensteering, a correlation matrix is computed for a MIMO channel on the basis of channel response matrices to obtain steering vectors. ND data symbol streams are transmitted on best spatial channels using steering vectors, where for N
    D =1 for principal mode eigensteering and N

For receiver eigensteering, a data symbol stream is steered toward a receive antenna on the basis of a steering vector obtained for that receive antenna. For all eigensteering schemes, a matched filter is derived for each receive antenna on the basis of the steering vector(s) and channel response vectors for the receive antenna.
