Inventors include Prathima Srinivasamurthy; Amarnadha Reddy; and Sreenath Ramanath.
The application for the patent was published on September 11, 2026, under issue no. 37/2026.
Abstract: Method and System to Encode Data for Efficient Bandwidth Utilization in DSSS Communication Systems Method (600) and system (102) to encode data for efficient bandwidth utilization in DSSS 5 communication systems is disclosed. The method (600) includes transmitting, by a transmitter (200), a first Pseudo Noise (PN) sequence without a payload data, acting as a reference sequence on an i channel, encoding, by a data encoder (210), by grouping N payload data bits to arriving at one of a 2^N possible combinations, selecting, by the transmitter (200), a second PN sequence through a chip shifting technique for generating a unique cyclic shifted version of the second PN 10 sequence corresponding to the encoded data, multiplexing, by a combiner, selected from the 2^N combinations of the cyclic shifted versions of the second PN sequence, and transmitting, by the transmitter (200), a multiplexed signal, the first PN sequence on the i channel and the cyclic shifted version of the second PN sequence on a q channel.
