Latest Patents

One of Sawan's latest patents is titled "System and method for bit interleaving of full-rate speech data." This invention presents a memory-efficient system and method for generating data blocks "on demand" for TDMA data bursts. In this embodiment, a GSM transmitter module converts forward error correction (FEC) coded full-rate speech frames into TDMA data blocks. The transmitter module includes a memory configured to store the FEC coded frames in both a current frame buffer and a previous frame buffer. An address generator is utilized to generate addresses of words in the current frame buffer during even clock cycles and addresses of words in the previous frame buffer during odd clock cycles. The memory provides the data words requested by the address generator to a multiplexer, which selects a bit from each of the data words as indicated by the intra-word bit offsets from the bit position generator. The stream of bits from the multiplexer forms the bit reordered and frame interleaved data for the data blocks.

Another significant patent by Sawan is "MLSE implementation using a general purpose DSP and shared hardware for a GSM application." This invention involves a digital signal processor (DSP), hardware module, and shared memory that work together to perform Viterbi decoding on a sequence of received symbols. Given channel coefficients, the DSP calculates initial data for Viterbi processing, including combination values for each possible state and branch product values for each possible symbol. These values are stored in shared memory for access by the hardware module, which is optimized to perform calculations associated with a single stage of the Viterbi algorithm.
