Many mobile devices and mobile networks utilize orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, the Doppler Effect and other noise or obstructions can cause OFDM signals to become entangled, particularly when the mobile device is moving, making the calculated position information inaccurate. Described herein are systems and methods for disentangling the OFDM signals by calculating a symbol length for the signals that is longer than the minimum symbol length, which is used in traditional OFDM. Selecting a longer symbol length reduces the Doppler Effect and other noise on the signals, making positioning calculations more accurate.
