Abstract Quality of Service (QoS) is critical for the success of real time applications over IP, such as Voice over IP (VoIP). On voice gateways, Call Admission Control (CAC) plays an important role for guaranteed QoS, for it makes decisions on whether and how to deliver the traffic based on different kinds of resources. In our study, we propose the(More)
The K-Best algorithm can achieve high BER performance with a large K value, but the complexity is very high. The RAKB algorithm reduces the complexity and gets similar BER performance compares to the K-Best algorithm. However, with the antennas increase, the BER performance improvement of the RAKB algorithm is not obvious. This paper presents an improved(More)
The detection of multiple-input multiple-output (MIMO) system is an important issue. The radius adaptive K-Best (RAKB) algorithm is proposed for the detection of the MIMO system, it decomposes the searching tree into several subbranches and provides similar bit-error-rate (BER) performance to the K-Best algorithm. But the complexity of the RAKB algorithm is(More)
