METHOD AND APPARATUS FOR SYMBOL TIMING TRACKING |
摘要 |
An apparatus and method for symbol timing tracking has a decimation index input (42). The decimation index (42) is connected to an upper threshold limiter (44) and a lower threshold limiter (46). The upper threshold limiter (44) is connected to an upper shift register (48). A plurality of cells (52) in the upper shift register (48) are connected to a majority vote logic circuit (54). The majority vote logic circuit (54) is connected to a symbol clock time base (56) and a clocking and clearing control circuit (62). The clocking and clearing control circuit (62) has a clock enable output and a clear signal connected to the upper shift register (48). The lower threshold limiter (46) is connected to a lower shift register (58) that is connected to a second majority vote logic circuit (60).
