CINRc = carrier to interference
plus noise ratio for center region,
The investigation focuses on three scheduling schemes such as Maximum Carrier to Interference (C/I) Proportional Fair and Round Robin.
We have performed a study on the performance of scheduling schemes such as Maximum Carrier to Interference Proportional Fair and Round Robin in multi cellular environment in HSDPA system at different user speed levels.
The criterion for interference to occur is for the victim receiver (Vr) to have a carrier to interference
ratio (C/I) less than the minimum allowable value.
While if the interference is greater than that value and the carrier to interference
(C/I) ratio is not enough, then the situation will be worse.
Key attributes of this new instrument include: 14-bit vertical resolution, sampling data rate operation from 800MSPS up to 2500MSPS, large output stage bandwidth from DC to 3GHz, excellent noise performance and high linearity (Noise Power Ratio: 45dB, Spurious Free Dynamic Range: 65dB, Carrier to Interference
The MS2721A performs a number of measurements including field strength, channel power, occupied bandwidth, adjacent channel power ratio (ACPR), and carrier to interference
The carrier to interference ratio (C/I) can in that case be calculated as:
Denoting the distance between hub 3 and the customers 1 and 2 as r, the carrier to interference ratio is given by:
