We propose a new turbo code noncoherent detection scheme based on a novel a-priori probability processor (APP). Using this method, many turbo encoders can be used without a change in the code or in the modulation, and without a significant change in the structure of the iterative decoder.

Proceedings of IEEE International Symposium on Information Theory, 2002
The turbo-decoding algorithm can be viewed as a message passing procedure on a graph. We contrast the standard "forward-backward" turbo-decoding algorithm with a new "concurrent" algorithm that is suited to parallel implementation.

Turbo codes are one of the most powerful error correcting codes. The VLSI implementation of Turbo codes for higher decoding speed requires use of parallel architectures. This paper explores the design spaces of both serial and parallel MAP decoders using graphical analysis.

Noncoherent sequence detection schemes for any coded modulation format have been previously proposed by the authors, which deliver hard decisions by means of a Viterbi algorithm. The current trend in digital transmission towards iterative decoding algorithms motivates an extension of these schemes.

The memory requirement for the uniform quantization turbo decoder is very large. The nonuniform quantization provides better or identical performance than the uniform scheme. But it is inconvenient for the latter to implement with the hardware circuits.

Selectable delay turbo decoding
2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002We present a method for selectable delay turbo coding that, using a common serially-concatenated encoding operation with interleavers of growing lengths, allows decoders having differing latency constraints to achieve decoding power commensurate with that delay.

Energy-efficient turbo decoder
IEEE International Conference on Acoustics Speech and Signal Processing, 2002Turbo codes have been recently adopted in the next generation of wideband CDMA standards. These codes achieve superior performance at the expense of high computational complexity. This makes their low energy implementation a very important yet challenging problem.
