modulation and coding schemeの例文
- To select the correct transmission speed or Modulation and Coding Scheme, a rate control algorithm may test different speeds.
- Various modulation schemes and coding rates are defined by the standard and are represented by a Modulation and Coding Scheme ( MCS ) index value.
- Under the best reception conditions, i . e . when the best EDGE modulation and coding scheme can be used, 5 timeslots can carry a bandwidth of 5 * 59.2 kbit / s = 296 kbit / s.
- In EGPRS / EDGE, the Modulation and Coding Schemes MCS-1 to MCS-9 take the place of the Coding Schemes of GPRS, and additionally specify which modulation scheme is used, GMSK or 8PSK . MCS-1 through MCS-4 use GMSK and have performance similar ( but not equal ) to GPRS, while MCS-5 through MCS-9 use 8PSK . In all EGPRS Modulation and Coding Schemes, a convolutional code of rate 1 / 3 is used, and puncturing is used to achieve the desired code rate.
