Disclosed is a method of, and apparatus for, processing a Random Access Channel (RACH) burst comprising a processed preamble group having at least two processed preambles. The processed preambles may be derived from short preambles, i.e., preamble comprising less than 887 bits, such that the RACH burst may be detected over shorter coherent accumulation time intervals relative to prior art coherent accumulation time intervals, thereby improving RACH burst detection. A transmitter generates a RACH burst comprising two or more processed preambles and transmits the RACH burst to a receiver. The receiver processes the RACH burst by correlating the two or more processed preambles to a plurality of reference signals in a frequency domain to produce a set of two or more frequency domain correlated outputs for each of the plurality of reference signals. The RACH burst is then detected based on energy associated with at least one frequency domain correlated output in the set of two or more frequency domain correlated outputs to a threshold energy value. |
