摘要: This work proposes a jointed mode detection and symbol detection scheme for DVB-T To reduce hardware complexity, the division operation of normalized maximum correlation (NMC) is removed and the delay line which uses twisted memory access method lowers the hardware cost. In addition, the proposed detection procedure does not need to refill or replenish the received data samples; as the result, the longest latency of the detection is only 17280 samples and is comparable with the parallel method. To lower the hardware cost, the memory is released for channel estimation after completing the Mode/GI detection and symbol detection. Total complexity of Mode/GI/symbol detection and channel estimation is about 200 Kgates (including memory)(1).
