    • A receiving apparatus includes a first transform unit configured to perform orthogonal transform on a time-domain input signal and perform saturation when an overflow occurs to transform the input signal into a plurality of frequency-domain signals, a second transform unit configured to perform orthogonal transform on the time-domain input signal while restricting the number of bits during orthogonal transform and continue operations while not performing saturation when at least one of the operations overflows and leaving the operation overflowing to transform the input signal into a plurality of frequency-domain signals, and a bit restricting control unit configured to control the number of bits during orthogonal transform by the second transform unit based on output signals of the first transform unit.
    • 一种接收装置,包括:第一变换部,被配置为对时域输入信号进行正交变换,并且在发生溢出时进行饱和,将输入信号变换为多个频域信号;第二变换部,被配置为进行正交变换 在时域输入信号中同时限制正交变换期间的位数,并且当至少一个操作溢出并且使操作溢出以将输入信号变换为多个频域信号时,继续操作而不执行饱和, 以及位限制控制单元,被配置为基于第一变换单元的输出信号来控制由第二变换单元正交变换期间的位数。
