Latest Patents
One of Shahri's latest patents is titled "Method and apparatus for an X-DSL modem supporting multiple X-DSL line codes." This innovative modem supports various line codes, including discrete multi-tone (DMT) and carrierless phase and amplitude (CAP). The modem is designed with components that form both a transmit path and a receive path. Key components include an encoder that encodes data into QAM symbols and DMT sub-symbols, as well as a Fourier transform component that facilitates the transformation of these symbols between frequency and time domains. This design allows for effective pulse shaping without the need for a discrete pulse shaping component in the transmit path.
Another patent involves count/address generation circuitry. This apparatus features two counters, each equipped with a count computation circuit and an upper bound circuit. The output of the first counter's upper bound circuit is linked to the second counter's circuits. Additionally, a lookup table is addressed by the current count value of the first counter, and a combining circuit receives the output from the lookup table along with the current count value of the second counter.
