Decision-Directed Coherent Delay-Locked PN Tracking Loop for DS-CDMAcoherent data detection. The performance of the proposed coherent DLL is evaluated by computer simulation. Computer simulation results show that it can significantly reduce the rms tracking jitter of the regenerated spreading code replica, thereby improving bit error rate (BER) performance in fading

Adaptive Beamforming for Wireless Communications In order to absorb more and more customers in a wireless communication system, we face the challenge of improving the system capacity without degradation in the quality of services. Moreover, the information also being transmitted in the form of data, besides voice, calls for a higher system reliab

Minimization of Outage Probability in Cellular Communication Systems by Antenna Beam Tiltinga patterns, carrier-to-interference ratios, and carrier-to-noise ratios are adressed..Our results show that determination of the optimum tilt angle is important especially for interference limited cells. For an antenna height in excess of 50m, missing the optimum tilt angle by 1° leads to an increas

Performance of RSS-, SIR-based Handoff and Soft Handoff in Microcellular Environmentshe desire to keep the handoff rate low, i.e., the risk for “flip-flopping” of the call between base stations should be minimized. Handoff decisions are usually based on estimates of what signal quality that can be provided by different base stations. These estimates can be constituted by, e.g., rece
