First Claim
1. In a communication system comprising a receiver and a plurality of sub-receivers, wherein signals received at each sub-receiver are forwarded to the receiver, a method for determining at which one of the plurality of sub-receivers a signal received at the receiver is received from, comprising:
- allocating a time delay to each sub-receiver;
delaying a signal received at each sub-receiver by the corresponding time delay; and
determining the presence of a received signal in a time window associated with each time delay, wherein a signal received in a time window associated with a particular time delay is determined to have been received by the corresponding sub-receiver.
