Wireless mobile devices are disclosed. A receiver to receive a coded signal having a code applied to the received coded signal includes a lower rate code comprising at least two code sequences of a higher rate code. One or more correlators are coupled with the receiver to correlate the received coded signal with the higher rate code to provide a higher rate code correlation result, to correlate the higher rate code correlation results with a first lower rate code to provide a first lower rate code correlation result, and to correlate the higher rate code correlation results with a second lower rate code to provide a second lower rate code correlation result. A comparator is coupled with the one or more correlators to compare the first lower rate code correlation result to the second lower rate code correlation result to determine presence of a signal indication.
