Network System

An encryption communication module on the side of a service providing server reports a global IP address allocated to an NAPT router on the service providing server side and a port number of an outside UDP header used on the global side to an authentication / key exchange server. When receiving an encryption packet from an encryption communication module on the user terminal side, the encryption communication module on the service providing server side overwrite a source / destination IP address of an inside IP header by a source / destination IP address of an outside IP header. The encryption communication module further changes a source port number of an inside TCP•UDP header to a unique value for each communication session in the encryption communication having the same source IP address in the outside IP header. The inverse header change is made when the packet is transmitted to the encryption communication module of the user terminal side.

Direct conversion receiver and DC offset reducing method

A determining section (18) and gain variation amount detecting section (9) detect a period having a possibility of a DC-component offset in an internal circuit of a direct conversion receiver increasing beyond an allowable value due to AGC operation, and during the period, a cut-off frequency of each of high-pass filters (12a to 12d) is set at a frequency higher than that in general operation, thereby rapidly converging transient responses of signals passed through the high-pass filters, while controlling precisely operation timings of reception power measuring section (16), gain calculating section (22), gain control section (23) and circuit power supply control section (24) composing an AGC loop, whereby the DC offset is prevented from increasing and stable circuit operation is assured. It is thereby possible to achieve further reductions in size and power consumption of a CDMA receiver using the direct conversion receiver.

Method and apparatus for allocating backhaul transmission resource in wireless communication system based on relay

In a relay based wireless communication system, a method for transmitting an uplink backhaul of a relay node includes obtaining scheduling information for an uplink backhaul sub-frame through a downlink backhaul control channel from a base station, and performing a rate matching and mapping of data by regarding at least one predefined symbol as a blank symbol. The predefined symbol is located at a front part or a rear part of the scheduled uplink backhaul sub-frame. The transmitting method further includes performing a multiplexing of the uplink backhaul sub-frame, and transmitting the multiplexed uplink backhaul sub-frame. This method can eliminate an overlap of transmission and reception timing in a relay node due to an RF transmission / reception switching time delay. Also, the method can make better use of wireless backhaul resources and minimize an influence on conventional systems by offering the compatibility with conventional uplink and downlink sub-frame structures.
