Abstract
In this paper, complementary code keying (CCK) transmission over frequency-selective fading channels is investigated. A vector signal model is introduced since CCK can be interpreted as a block code. Based on pairwise error probabilities we derive a performance approximation for optimum detection obtained for given channel statistics, and compare the theoretical results with simulations. Because optimum maximum-likelihood sequence estimation (MLSE) is not practical for large channel delay spreads, minimum mean-squared error decision-feedback equalization (MMSE-DFE) is employed. Two different DFE approaches are considered here: (a) the conventional scalar DFE and (b) a block-based DFE, which is well suited for the underlying vector signal model. For various common indoor channel profiles, numerical results are given for MLSE, scalar DFE and block DFE in terms of bit error rates (BERs) and packet error rates (PERs).
