Latest Patents
Vellenki Umapathi Reddy holds a patent for a "Method and apparatus for channel characterization in direct sequence spread spectrum based wireless communication systems." This invention provides a method and apparatus for multi-path channel characterization in a Direct Sequence Spread Spectrum based wireless communication system. The multipath channel is modeled as a tapped delay line FIR filter with L taps corresponding to L paths. A pre-defined training sequence is transmitted over the multipath channel. The received signal is sampled, and cross correlations are computed between the samples obtained and the spreading sequence for various time lags to obtain the symbol boundary. Thereafter, a desired set of L cross correlations for L time lags around the symbol boundary is estimated. For this, all the L possible sets of L cross correlations for L time lags around the symbol boundary are considered. The energy in the cross correlations corresponding to each considered set is calculated. The set of L cross correlations having the maximum energy is selected for tap computation. The tap coefficients are estimated by solving a set of L simultaneous linear equations. This innovative method has the potential to significantly improve the efficiency of wireless communication systems.
