System, base station and method for supporting frequency domain equalization for frequency domain equalization-capable mobile stations and supporting improved channel estimation for both time domain and frequency domain equalization-capable mobile stations on the forward link without the necessity of modifications to an air-interface specification of a legacy communication system. A first signal sequence is generated according to a first format and an offset vector is also generated. The first signal sequence and the offset vector are combined to form a second signal sequence according to a second format. The second signal sequence of said second format supports frequency domain equalization in one or more frequency domain-capable mobile stations. The second signal sequence maintains compatibility with one or more legacy mobile stations.
