Abstract

Apparatus, and an associated method, for acting upon data signals received at a base station (110) of a fixed wireless access communication system (100). A plurality of modems (302/304) are positioned at the base station (110), and a controller (314) controls to which modem (302/304) that a data signal, transmitted by a particular subscriber station (121-123), is applied to a particular modem (302/304). Profiles relating to channel and signal characteristics are also maintained and used by the modem (302/304) during demodulation operations.
