SCHEDULING FOR MASSIVE MIMO USING CHANNEL AGING UNDER QOS CONSTRAINTS

of the channel estimator has a critical e ff ect on the perfor- mance of the receiver [13, 14]. In SISO communications, channel estimators can either use the training sequence or not. Although the distribution of training symbols in a block of data a ff ects the performance of systems[r]

The Idealized Wireless Fair Queuing (IWFQ) simulates an error-free channel by applying a compensation model on top of the WFQ scheduler [25]. A start tag and a finish tag are associated to each packet, as for WFQ. The flows are serviced according to increasing service tags of the flows pe[r]

As an effective solution to the tradeoff between array size and the number of antenna elements, dual polarization antenna is widely utilized in massive MIMO systems. However, existing channel state information (CSI) feedback schemes are not suitable for dual-polarized massive MIMO as they ignore the[r]

the dual problems of maximizing expected throughput given limited energy and of minimizing expected energy given the minimum throughput constraint.
The above works have significantly enhanced the overall performance of wireless communications. However, they did not consider the scheduling p[r]

13.3 USE OF HIERARCHY
Floorplanning and prototyping may be flat or hierarchical. In a flat floorplan, the entire design is treated as a single problem, and any cell or block can be placed at any location in the design. There is no need to assign cells and pins to the blocks, or create block budget[r]

This paper presents a method of calendar (weekly) scheduling for production teams, when the average orders utility function is used as the quality criterion. The method is based on the concept of “production intensity”, which is a dynamic parameter of production process. Applied software package all[r]

[Channel Selling Unit Productivity * Number of Units * Rate per Unit For example:
Telemarketing: 100 telemarketers * 10 units per day * $10 per unit = $10,000/day Sales force: 100 sales reps * 1,000 units per week * $10 per unit = $1,000,000/week R[r]

“Hard” linguistic constraints, such as these, tend to affect mostly the “core grammatical func- tions”, i. e. the argument functions (rather than e. g. adjuncts) of a particular predicate. As these functions constitute the core meaning of a sen- tence (as in: who did what to whom), it is impo[r]

The Soil Constraints and Management Package (SCAMP) has been developed to identify soil constraints to crop production by considering a range of key soil properties (Moody and Phan Thi Cong 2008; Moody et al. 2008). Once these constraints have been identi[r]
