  This paper investigates the positioning of the pilot symbols, as well as the
power distribution between the pilot and the communication symbols in the OTFS
modulation scheme. We analyze the pilot placements that minimize the mean
squared error (MSE) in estimating the channel taps. In addition, we optimize
the average channel capacity by adjusting the power balance. We show that this
leads to a significant increase in average capacity. The results provide
valuable guidance for designing the OTFS parameters to achieve maximum
capacity. Numerical simulations are performed to validate the findings.
