Beetles of that era came in two body styles — hard-top and cabriolet — and with one powertrain option: air-cooled, rear-engine, three-speed manual transmission.
Algorithms currently used for high speed data transmission over voice-band channels can be based on following three principles: on LMS criterion, on ls criterion or on artificial neural network.
高速数据传输中信道均衡算法大致分为三类：即基于LMS准则、LS准则和人工神经网络的自适应算法。
