Carrier Synchronization in Software Defined Radio for 8psk
نویسندگان
چکیده
Abstract The main aim behind the growth of software defined radio is the skill to reconfigure radios, thereby increasing the efficiency in the usage of radio resources. In wireless communication the multipath effect produce interference and also changes in the phase of the signal. In order to correctly recover the transmitted data with minimum error, carrier synchronization is essential. One of the challenging tasks in a communication system is synchronization of the carrier signal. In this paper 8PSK modulation scheme is used for data transmission. Since 8PSK achieves high data rate, the probability of actual signal recovery is quite difficult. Here the carrier recovery for 8PSK modulation has been performed.

Maximum likelihood carrier phase synchronization in FPGA-based software defined radios
Digital signal processing techniques are applied to maximum likelihood carrier phase synchronization for QPSK and QAM in an all-digital sampled data receiver. To achieve the flexibility required by modern Software Defined Radios (SDR’s), this task must either be performed in a DSP processor (reconfigurable software) or in an FPGA (reconfigurable hardware). This paper describes the design proces...

Although the extensive research works have been carried out over the last two decades to resolve the problem of carrier synchronization, it remains today an issue of paramount importance for many recent digital communication systems such as the emerging wireless technologies of Software Defined Radio (SDR) and Cognitive Radio (CR). Indeed, SDR systems are multi-functional and flexible such that...
متن کاملA Phase Locked Loop with Arbitrarily Wide Lock Range for Software Defined Radios
Phase locked loops (PLLs) are frequently used in Software Defined Radios (SDR) for carrier recovery and symbol timing synchronization. Unfortunately, conventional PLLs can function correctly only when the frequency offset remains within a relatively small and limited range. This limited lock range is a direct consequence of the inability of the phase detector to resolve any phase error that lie...

Our paper deals with a Dynamic Spectrum Access (DSA) and its implementation on a Software Defined Radio (SDR) for IEEE 802.15.4e Networks. The network nodes select the carrier frequency after Energy-Detection based Spectrum Sensing (SS). To ensure frequency hoping between two nodes in IEEE 802.15.4e Network, we propose a synchronization algorithm. We considerate the IEEE 802.15.4e Network is Se...
