Successive interference cancellation is performed with improved computational efficiency while offering performance approaching that of full CRC-based successive interference cancellation. In a “blind” interference cancellation technique, reconstructed streams are used for interference cancellation without regard to whether the reconstructed streams were properly decoded. In a “semi-blind” interference cancellation technique, decoder outputs from linear equalization can be used instead of decoder outputs from successive interference cancellation in those cases where linear equalization produces accurate decoding but successive interference cancellation does not.
