1. A method performed in a receiver, comprising:
configuring the receiver to select a despreading gain;
providing for symbol-rate synchronous channelizing of a received signal that comprises at least two navigation signals, to produce a plurality of frequency channels;
combining the plurality of frequency channels to produce a combined signal; and
estimating the position of the receiver using the combined signal.
