BPSK：二進制相移鍵控 (BPSK: Binary Phase Shift Keying)
BPSK is an abbreviation of "Binary Phase Shift Keying".
BPSK是“二進制相移鍵控”的縮寫 。
BPSK is also occasionally called phase reversal keying (PRK), or 2PSK, which is the elementary form of phase-shift keying (PSK). Phase Shift Keying is a progression of the digital modulation method, which processes the transmission of data by modulating the phase of a carrier wave. The process of this transmission is achieved by changing the phase of sine and cosine inputs at a specific instance of time. The method of Phase Shift Keying is commonly used for wireless LANs, bio-metric, contactless operations, all along with RFID and Bluetooth communications.
BPSK有時也稱為相反轉鍵控(PRK)或2PSK ，它是相移鍵控(PSK)的基本形式。 相移鍵控是數字調制方法的一種進步，它通過調制載波的相位來處理數據的傳輸。 通過在特定時間更改正弦和余弦輸入的相位來實現此傳輸過程。 相移鍵控方法通常用于無線LAN，生物識別，非接觸式操作以及RFID和藍牙通信。
In the process of BPSK, it is a progression of a two-phase modulation system of the method, in which the sine wave carrier signal acquires two different phase reversals, 0's and 1's in a binary format.
在BPSK的過程中，這是該方法的兩相調制系統的發展，其中正弦波載波信號以二進制格式獲取兩個不同的相位反轉，即0和1。
In case of binary 1, θ = 0°
在二進制1的情況下，θ= 0°
In case of binary 0, θ = 180°
在二進制0的情況下，θ= 180°
BPSK的優勢 (Advantages of BPSK)
In the process of transmission, modulated data of BPSK can pass through longer distances, when it transmitted initially from the base station or subscriber stations because of the property that the sine wave carrier signal acquires two different phase reversals, 0's and 1's in a binary format.
在傳輸過程中，由于BPSK的調制數據最初從基站或用戶站傳輸時，由于正弦波載波信號以二進制格式獲取兩個不同的相位反轉(0和1)，因此它可以通過更長的距離。 。
Modulation of BPSK is used by the majority of cellular towers for communication of long distances or transmission of the data.
大多數蜂窩塔使用BPSK調制來進行長距離通信或數據傳輸。
In the recovery process of indigenous binary information, the BPSK demodulator needs to make simply two decisions. For this reason, in comparison to additional modulation categories, the BPSK receiver is extremely fundamental.
在本地二進制信息的恢復過程中，BPSK解調器只需做出兩個決定。 因此，與其他調制類別相比，BPSK接收機極為重要。
BPSK is power efficient modulation system of the method as in the process of transmission; a smaller amount of power is considered necessary to transmit the carrier signal data with less number of bits.
BPSK是在傳輸過程中的高效節能調制系統； 認為以較少的位數發送載波信號數據需要較少的功率。
BPSK的缺點 (Disadvantages of BPSK)
In the system of method of BPSK modulation, one bit is transmitted by one particular analog carrier signal. Therefore, there is a similarity between data rate in bits per second and the symbol rate.
在BPSK調制方法的系統中，一個特定的模擬載波信號發送一位。 因此，每秒的數據速率(以比特為單位)與符號速率之間存在相似性。
In contrast to further modulation categories, BPSK is not bandwidth efficient modulation system of method.
與其他調制類別相反，BPSK不是帶寬有效的調制系統方法。
