Elaborate a step-by-step procedure for the adaptive codebook search, including all equations and decision strategies. Take into account the integer and fractional parts of the pitch period, as well as the number of sub frames. Consider the following cases of search strategies:

(a) Full search: Every possible code vector is computed with the best returned.

(b) Suboptimal search: The integer part of the pitch period is first located, followed by a fractional refinement near its neighbor.
