Latest Patents
Madhukumar holds a patent for a CDMA system with frequency domain equalization. This innovative system describes methods for processing symbol blocks of a spread signal in both frequency and time domains. The transmitter of the CDMA system spreads pilot symbols and data of the symbol blocks to derive a spread sequence. This spread sequence is then extended with a predetermined number of chips and pulse shaped for transmission as the spread signal. The receiver of the CDMA system receives the spread signal, removes the predetermined number of chips, and orthogonally transforms the spread signal to the frequency domain to derive a transformed signal. The transformed signal is equalized in the frequency domain to derive an equalized signal, which is then inverse orthogonally transformed to an output in the time domain. Finally, the output is despreaded to derive the symbol blocks.
