Parallel punctured convolutional encoder |
摘要 |
A parallel punctured convolutional encoder (44) that provides convolutional coding of a stream of digital data bits in a parallel manner for high frequency transmission. The parallel convolutional encoder (44) includes a plurality of one-bit delay devices (46-56) and four XOR gates (78-84). Three consecutive bits are applied to the convolutional encoder (44) in a parallel manner and four polynomial expressions are provided from the XOR gates 78-84 in a parallel manner at each clock cycle, where certain values in the polynomial expressions are provided and certain values are not provided to conform with a particular puncture scheme of a desirable convolutional rate. In an altnerate embodiment, a concatenated Reed-Solomon TCM QAM encoder is provided that operates on parallel lines of digital data for high frequency communications systems.
