The present invention provides a method and apparatus for preventing show-thru (and therefore misinsertion of unintended traffic) among uplink beams transmitted to a satellite. The method includes the steps of selecting (402) an uplink A stagger value, selecting an uplink B stagger value, coding (404) uplink A data to generate coded uplink A data, and coding (406) uplink B data to generate coded uplink B data. Subsequently, the method transmits (412) the coded uplink A data, staggered by the uplink A stagger value, in the uplink A and further transmits (414) the coded uplink B data, staggered by the uplink B stagger value, in the uplink B. During coding (404, 406), the method may use a full length error correcting code capable of correcting t errors. In such a case, the method generally selects an uplink B stagger value differing from the uplink A stagger value by more than t codeword symbols. Alternatively, the method, during coding (404, 406), may use a shortened error correcting code capable of correcting t errors. In such a case, the method generally selects an uplink B stagger value differing from the uplink A stagger value by at least one codeword symbol. The method is not limited to any particular number of uplink beams and may provide staggering for all same color uplink beams in a predetermined reuse pattern, for example.
