Abstract

Problems of noise emission during transmission in successive time slots (A-B) in mobile telephony are solved by causing the transmitted power to change in a monotonic manner from a previous value to a new value. It is shown that this increases the transmission bit rate.

Claims

1. A method of transmitting data in a radio communication system in a plurality of successive time slots (A, B) in the same transmission frame, wherein the transmitted power of a transmitter is modified monotonically between one time slot and the next time slot in the same frame, wherein the modification includes multiplications (coefficient*(B−

A)+A) of standardized values by the power differences between the two successive time slots and adding the power of the preceding slot to the results of those multiplications.

2. A method according to claim 1, wherein the modification is a monotonic increasing modification.

3. A method according to claim 1, wherein the modification includes reading a power set-up memory by means of a reader and slaving the transmitted power to the value read in that set-up memory.

4. A method according to claim 3, wherein the modification includes loading a cache by means of a microprocessor during a time slot and transferring the content of the cache into the set-up memory before reading the set-up memory.

5. A method according to claim 1, wherein a transmit signal is modulated by meaningful bits of data to be transmitted during monotonic modification of the transmitted power.

6. A method according to claim 1, wherein the modification is of the cosine type.
