Abstract
A data portion measuring section 103 measures a reception level of a data portion of a received signal, and a pilot portion measuring section 104 measures a reception level of a pilot portion of the received signal. A comparing/selecting section 105 compares the reception level of the data portion with that of the pilot portion, and selects a higher reception level. An AGC gain value calculating section 106 calculates an AGC gain value from the higher reception level selected by the comparing/selecting section 105 and an input allowable level of A/D conversion.
Claims8
A radio receiving apparatus comprising:
- a receiver for receiving a signal including a first portion and a second portion each having a different reception level;
- a measure for measuring a reception level of the first portion and a reception level of the second portion;
- a compare/selector for comparing the reception level of the first portion with the reception level of the second portion to select a higher reception level;
- and
- a calculator for calculating a level control value using the reception level selected by said compare/selector, wherein
- said receiver controls the level of the signal including the first portion and the second portion in accordance with the level control value.
A communication terminal apparatus having a radio receiving apparatus, said radio receiving apparatus comprising:
- a receiver for receiving a signal including a first portion and a second portion each having a different reception level;
- a measure for measuring a reception level of the first portion and a reception level of the second portion;
- a compare/selector for comparing the reception level of the first portion with the reception level of the second portion to select a higher reception level;
- and
- a calculator for calculating a level control value using the reception level selected by said compare/selector, wherein
- said receiver controls the level of the signal including the first portion and the second portion in accordance with the level control value.
A base station apparatus having a radio receiving apparatus, said radio receiving apparatus comprising:
- a receiver for receiving a signal including a first portion and a second portion each having a different reception level;
- a measure for measuring a reception level of the first portion and a reception level of the second portion;
- a compare/selector for comparing the reception level of the first portion with the reception level of the second portion to select a higher reception level;
- and
- a calculator for calculating a level control value using the reception level selected by said compare/selector, wherein
- said receiver controls the level of the signal including the first portion and the second portion in accordance with the level control value.
A radio receiving method comprising the steps of:
- receiving a signal including a first portion and a second portion each having a different reception level;
- measuring a reception level of the first portion and a reception level of the second portion;
- comparing the reception level of the first portion with the reception level of the second portion to select a higher reception level;
- calculating a level control value using the selected reception level;
- and
- controlling the level of the signal including the first portion and the second portion in accordance with the level control value.
