New results on adaptive computational resource allocation in soft MIMO detection
The fundamental problem of our interest is soft MIMO detection for the case of block fading, i.e., when the transmitted codeword spans over several independent channel realization...

Coding of unquantized spectrum sub-bands in superwideband audio codecs
We present several new methods for coding of spectrum coefficients in embedded audio codecs. In audio codecs, the spectrum is often divided in sub-bands, and quantized using a vec...
