CDMA

In satellite communications, CDMA (Code Division Multiple Access) is used to manage multiple simultaneous signals over a single channel. Each signal is encoded with a unique code, which allows the system to distinguish between different transmissions. This is particularly useful in satellite networks to efficiently use the available bandwidth and to minimize interference between users. … Read more

A CDMA operator is a mobile network provider that uses Code Division Multiple Access (CDMA) technology to provide wireless communication services. CDMA allows multiple users to share the same frequency channel by assigning unique codes to each user’s data, enabling efficient use of the available spectrum. What are CDMA operators? CDMA operators are mobile carriers … Read more

Quadrature Amplitude Modulation (QAM) and Quadrature Phase Shift Keying (QPSK) are both digital modulation schemes, but they differ in how they encode data onto the carrier signal. QAM is often preferred over QPSK in certain scenarios due to its higher data-carrying capacity and spectral efficiency. Let’s explore in detail why QAM is preferred over QPSK: … Read more

Binary Phase Shift Keying (BPSK) is a digital modulation scheme that falls under the broader category of phase shift keying (PSK). It is a fundamental modulation technique used in digital communication systems to transmit binary data. Let’s delve into the details of the type of modulation that BPSK employs: 1. Basic Principles of BPSK: Phase … Read more

Offset Quadrature Phase Shift Keying (OQPSK) is a modified version of Quadrature Phase Shift Keying (QPSK) that addresses certain issues associated with traditional QPSK modulation. OQPSK introduces an offset in the timing of the transmitted signal to improve spectral efficiency and minimize the occurrence of transitions at symbol boundaries. Let’s explore in detail why OQPSK … Read more
