Abstract: The present invention relates to use of a smart antenna for a RF reader on a Radio Frequency Identification (RFID) system to significantly increase the operating range of the RFID system. The smart antenna can be an adaptive antenna array. The smart antenna comprises a plurality of antenna elements and, by combining the signals from multiple antenna elements, significantly increases the received signal-to-noise ratio. In a noise limited environment, combining the signals to maximize the received signal-to-noise ratio can be based on the maximal ratio combining (MRC) principle. To achieve the best signal quality, the received signal from each antenna can be phase-shifted such that the resultant signals from all antennas are in phase. In addition, the signal from each antenna can be scaled in amplitude based on the square root of its received signal-to-noise ratio.

Abstract: The present invention comprises a method and system for weight generation in an adaptive array with spread spectrum signals. Signals received by each antenna are amplified, weighted and summed. Complex weighting is achieved by splitting the signal into inphase and quadrature components, and adjusting the gain of each of these components before combining these weighted components. The output signal after combining of the weighted signals from each antenna is downconverted to baseband, creating inphase and quadrature baseband components. The baseband components are multiplied by the spread spectrum sequence to despread the output signal and reduce the bandwidth of the desired spread spectrum signal to the original desired signal bandwidth. The signals received by each antenna are also downconverted to baseband inphase and quadrature components. Each of these components is multiplied by the spread spectrum sequence to despread the output signal and reduce the bandwidth of the desired spread spectrum signal to the original desired signal bandwidth. The despread/filtered individual antenna signals are multiplied by the despread/filtered output signal to generate antenna weights.

Abstract: The present invention provides a method and system for operating a wireless communication system in which received signals from a plurality of antennas are weighted and combined with a beam forming operation to form an output signal. The beam forming operation determines weights adjusted to increase a desired signal power in the output signal while reducing the power in the output signal of out-of-band components. In an embodiment of the present invention, beam forming operations are performed with maximal ratio combining (MRC). Alternatively, a constant modulus algorithm (CMA) can be used for beam forming operations. In an alternate embodiment, improved interference suppression is performed with a novel algorithm referred to as an interference nulling algorithm (INA). The INA receives an error signal which is 180° out of phase with a combination of the channels for individual antennas, referred to as the SUM channel. The error signal is determined by complex conjugate multiplication of the individual signals and a reference complex signal. It is desirable to simultaneously achieve diversity and combining gain and suppress the adjacent channel by combining the weight generation for MRC and that for INA, as described above, to generate antenna weights similar to those of MMSE combining.

Abstract: A smart external antenna module is proposed for wireless systems. The module allows the advantages of smart antennas to be easily added to existing wireless systems without any modification to the transceiver. Specifically, the smart antenna module weights and combines the signals received by multiple antennas to improve the received signal quality, and then when it detects that there is a signal to be transmitted by the transceiver, it turns off the receiver, turns on the transmitter and uses the receive weights to transmit the signal out of the multiple antennas to improve signal reception at the desired user. Such a module can be added to the external antenna port of an existing transceiver with no change to that transceiver.
