We apply Lusztig’s theory of character sheaves to the problem of calculating the spherical functions of $G(\mathbb {F}_{q^{2}})/G(\mathbb {F}_q)$, where $G$ is a connected reductive algebraic group. We obtain the solution for generic spherical functions for any $G$, and for all spherical functions when $G=GL_n$. The proof includes a result about convolution of character sheaves and its interaction with the associated two-sided cells.
