Latest Patents

One of Heidari's latest patents focuses on multi-modulus frequency dividers. This invention relates to various embodiments of multi-modulus frequency dividers, devices that include the same, and associated methods of operation. The method of operating a multi-modulus divider (MMD) involves receiving an input signal at a first frequency and generating an output signal at a second, lower frequency based on a divisor value. Additionally, the MMD can receive an integer value and set the divisor value equal to this integer in response to its current state matching a common state, allowing for flexibility in operation.

Another significant patent by Heidari addresses channel estimation in OFDM communication systems. This invention includes an OFDM receiver circuit that features an FFT circuit designed to calculate an FFT of multiple sample values received by the receiver. Furthermore, a smoothing circuit is incorporated to identify equalizer coefficients for the sample values by truncating portions of the impulse response of the FFT.
