One aspect of the invention simultaneously estimates data transmitted in a spread spectrum communication system using different spreading factors. A plurality of communication signals are received. Each communication signal has an associated code. At least two of the communication signals has a different spreading factor. The transmitted data is estimated as estimated symbols using codes of a uniform spreading factor. For data transmitted with a spreading factor other than the uniform spreading factor, the estimated symbols of that data is converted to symbols of the code of that data. Another aspect of the invention receives a spread spectrum communication signal having data spread using a plurality of spreading factors. The data of the communication is estimated as estimated symbols using codes of a uniform spreading factor. The estimated symbols are parsed into parcels, where the estimated symbols correspond to data transmitted with a same spreading factor. For parcels not of the uniform spreading factor, the estimated symbols are converted into symbols of the same spreading factor of that parcel.
