In this letter, we optimize the pilot overhead in communication with retransmission and investigate the dependence of this overhead on various system parameters, e.g., fading rate, target rate, and signal-to-noise ratio. We formalize the optimization and frame it in terms of throughput maximization; this leads to an accurate optimal pilot overhead closed-form expression. Results show that the optimal overhead expressions are roots of quartic polynomials. At a high-power regime, they decrease with the target rate and increase with the normalized Doppler frequency, and at low-power regime, they are only function of the target rate. |
