Low complexity joint detection for UTRA-TDD receivers
Luca Fanucci, Riccardo Grasso · 2003
In this paper, we present the successful application of prime factor algorithm FFT (Fast Fourier Transform) and pruning techniques to achieve low complexity UTRA-TDD joint detection. This approach has been applied to the Minimum Mean Square Error-Block Linear Equalizer (MMSE-BLE) receiver after proper reformulation in the frequency domain. A complexity reduction of 50% with respect to previous solutions has been demonstrated without any performance loss.
