Abstract

This paper considers a frequency-domain synchronization/channel decoding procedure for systems employing TCH-based training blocks (Tomlison, Cercas and Hughes). Using the fact that an N-point Discrete Fourier Transform (DFT) can be partitioned into M smaller DFTs we present a procedure for simultaneous decoding/despreading and synchronization that can switch between 16 bit-length and 256 bit-length cyclic codes.
