Abstract:
A method and system for increasing data rate in a mobile terminal using spatial multiplexing for digital video broadcasting for handhelds (DVB-H) communication are provided. A reconfigurable orthogonal frequency division multiplexing (OFDM) chip may be utilized in a mobile terminal to process received spatially multiplexed signals. The mobile terminal may be utilized in a spatially multiplexed multiple-input-multiple-output (SM-MIMO) wireless system. The spatially multiplexed signals may be quadrature phase shift keying (QPSK) modulated and may utilize OFDM subcarries. A processor may be utilized to configure the OFDM chip to process signals such as IEEE 802.11 and 802.16, and DVB. The OFDM chip may generate channel weights to be applied to the spatially multiplexed signals received in multiple receive antennas. The weighted signals may be combined to generate multiple RF received signals from which channel estimates may be generated. Subsequent channel weights may be dynamically generated from generated channel estimates.
