The present invention involves a forward error correction technique for use in wireless telecommunications systems, where a first convolutional coding sche me is applied to the bits in a first portion of a data block and a second convolutional coding scheme is applied to the bits in a second portion of th e data block, and where the second portion of the data block may encompass a part of the data block or the entire data block, including the first portion . The first and the second coding scheme may be implemented using the same convolutional coding scheme with a first and a second puncturing scheme respectively. While the first coding scheme employs a first code rate, the second coding scheme employs a second code rate that is higher than the firs t code rate. The higher rate makes it possible to incorporate the one or more tail bits into the second portion of the data block. In so doing, generation of additional symbols, such as orthogonal frequency division multiplexing symbols, can be avoided.
