Implementation of a Low-Complexity MMSE Turbo-Equalizer on the TMS320VC5509

چکیده
This report describes the implementation of a low-complexity minimum mean-square error (MMSE) turbo-equalizer on Texas Instruments TMS320VC5509 device, a low-cost 16-bits fixed-point DSP with low power consumption designed for mobile handsets. A data rate of 207 Kbits/s per iteration has been obtained with programming mainly in C. With carefully optimized data quantization, the resulting fixed-point receiver exhibits virtually no performance loss with respect to an ideal (unquantized) floating-point turbo-equalizer.

Turbo-equalization for bandwidth-efficient digital communications over frequency-selective channels
This thesis deals with the problem of combining equalization with decoding for high data ratebandwidth-efficient transmissions over frequency-selective channels. Specifically, we focus on Turbo-Equalization which establishes an exchange of soft information between the equalizer and the decoderin an iterative manner. We first consider MAP turbo-equalizers which rely on trellis-based ...

It is proposed low-complexity block turbo equalizers for orthogonal frequency-division multiplexing (OFDM) system in a channel. The presented work is based on a soft minimum mean –square error (MMSE) block linear equalizer (BLE) that exploits the banded structure of the frequency –domain channel matrix, as well as a receiver window that enforces this banded structure. This equalization approach...
متن کاملMinimum mean squared error equalization using a priori information
A number of important advances have been made in the area of joint equalization and decoding of data transmitted over intersymbol interference (ISI) channels. Turbo equalization is an iterative approach to this problem, in which a maximum a posteriori probability (MAP) equalizer and a MAP decoder exchange soft information in the form of prior probabilities over the transmitted symbols. A number...

This paper investigates the realization of an efficient low-complexity turbo-equalizer under fixedpoint data representation and computation constraints. We address the quantization issues that arise in the receiver design, and expose a simple computation procedure for the equalizer coefficients. The proposed solution is well-suited for a DSP implementation on low cost 16 bits fixed-point device...
