Latest Patents

One of Kanu Chadha's latest patents is titled "Receiver architecture for pilot based OFDM systems." This invention introduces a novel methodology and apparatus for clock-offset compensation and common-phase offset correction in Frequency Division Multiplexing based wireless local area network (WLAN) environments. The invention employs a curve fit, such as a threshold-based least mean squares (LMS) fit of the phase of the pilot sub-carriers in each OFDM symbol. This approach estimates and counteracts the rotation of data sub-carriers due to residual frequency offset, low-frequency phase noise, and clock offset. It is particularly effective in wireless channels with multipath, where pilots typically experience frequency-selective fading. The thresholding LMS is implemented in a hardware-efficient manner, providing cost advantages over a weighted-LMS alternative. Additionally, the invention utilizes a unique phase-feedback architecture to eliminate the effects of phase wrapping and avoids the need to refine channel estimates during packet reception.

Another significant patent is the "Method and system for dynamically reducing length of a delay chain." This invention addresses the challenge of latency in hardware implementations of 802.11a OFDM receivers with long delay chains. Upon a triggering event, the delay chain shifts data out at a higher rate than incoming packets, while a processor controls bypassing circuitry to reduce latency. The proposed scheme implements dynamic reduction in the depth of the delay chain once timing recovery has been performed, achieving exponential reduction in the number of elements in the delay chain at each step.
