Abstrakt: This letter looks at the effects of mobility and diversity. The transmitter is mobile in this scenario, while the receivers are diverse. The mobile transmitter will induce a doppler effect on the signal being sent. The receiver antennae will be able to estimate the doppler effects and remove them. It will then leverage the multiple antennae to improve the reception of the signal. Doing both improves the packet detection rate in a low signal to noise ratio (SNR) scenario. When multiple mobile transmitters are used, the packet detection rate in a low SNR environment was poor.
