The invention discloses a coding method for reducing power consumption of a feed-forward equalizer, and relates to the technical field of equalizer coding, and the coding method is characterized in that each bit is only a value {-1, 0, + 1}; adjacent bits cannot be non-zero at the same time; a first non-zero bit symbol from a high bit to a low bit must be consistent with the overall symbol; the code decomposes the input data into a few symbolized weight bits, and multiplication of the input data and the weight can be converted into shift and addition or subtraction operation. Therefore, for a single tap, corresponding multiplication operation can be realized through shifting and addition or subtraction, and final output can be obtained through summation finally. According to the invention, equivalent multiplication can be completed through a limited number of shift and addition; during implementation, a multiplier is not needed, only symbol control addition is needed, and a very efficient digital system is achieved through the encoding mode and is used for achieving multiplication, especially on occasions needing high throughput rate and low delay.

Methods, systems, and devices for wireless communications are described. In some examples, a first device may generate and transmit multiple shaped symbols based on a state for each shaped symbol. To generate each shaped symbol, the first device may normalize the state for each symbol in accordance with a range interval. If the state is outside the range interval, the first device may receive and convert bits from a bit buffer to generate the shaped symbol and normalize the state to be within the range interval. A second device may receive the multiple shaped symbols and generate information bits for each shaped symbol. Once the second device has received all of the shaped symbols of the sequence of shaped symbols, the second device may obtain a deshaped information vector based on the information bits generated for each shaped symbol and a state for a last shaped symbol.

As the maximum number of speed levels in a sound velocity meter increases, the number of musical pieces and other materials required also increases. Therefore, understanding the number of speed levels, which is determined by the number of superimposed musical pieces, becomes increasingly difficult as the number of levels increases. [Solution] The number of steps in the speed range of the sound velocity meter is changed from the usual decimal system to a positional numeral system of a lower value. By reducing the number of digits used in each digit of the new numeral system, the total number of musical pieces required is reduced, and consequently the maximum number of overlapping musical pieces is reduced, making it easier to understand the number of steps in the speed range by hearing.
